He was the son of a tenant farmer, John McLagan, and Girzel \u2018Grace\u2019 McLagan, n\u00e9e McInroy. McLagan senior had travelled to Demerara (modern-day Guyana) by around 1797, where his uncle, <a href=\"https:\/\/www.spanglefish.com\/slavesandhighlanders\/index.asp?pageid=552969\" target=\"_blank\" rel=\"noreferrer noopener\">James McInroy,<\/a> was an enslaver, merchant trader and plantation owner.

Two of these plantations were the Coffee Grove and Caledonia estates. In 1820 467 enslaved persons were recorded on both estates, where a mixture of coffee, sugar and cotton were grown.&nbsp;The slave-produced coffee, sugar and cotton (and rum) was exported primarily to the UK, where it was distributed by the Liverpool and Glasgow partner branches of McInroy, Sandbach and Co.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/i0.wp.com\/historyofparliament.com\/wp-content\/uploads\/2025\/12\/4613065-Arrowsmith-1842-Map.jpg?ssl=1\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"720\" height=\"507\" data-attachment-id=\"19266\" data-permalink=\"https:\/\/historyofparliament.com\/2025\/12\/11\/peter-mclagan-senior-1774-1860\/4613065-arrowsmith-1842-map\/\" data-orig-file=\"https:\/\/i0.wp.com\/historyofparliament.com\/wp-content\/uploads\/2025\/12\/4613065-Arrowsmith-1842-Map.jpg?fit=2960%2C2084&amp;ssl=1\" data-orig-size=\"2960,2084\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;1&quot;}\" data-image-title=\"4613065-Arrowsmith 1842 Map\" data-image-description=\"\" data-image-caption=\"\" data-medium-file=\"https:\/\/i0.wp.com\/historyofparliament.com\/wp-content\/uploads\/2025\/12\/4613065-Arrowsmith-1842-Map.jpg?fit=300%2C211&amp;ssl=1\" data-large-file=\"https:\/\/i0.wp.com\/historyofparliament.com\/wp-content\/uploads\/2025\/12\/4613065-Arrowsmith-1842-Map.jpg?fit=720%2C507&amp;ssl=1\" src=\"https:\/\/i0.wp.com\/historyofparliament.com\/wp-content\/uploads\/2025\/12\/4613065-Arrowsmith-1842-Map.jpg?resize=720%2C507&#038;ssl=1\" alt=\"A map of British Guiana with three locations (Caledonia, Coffee Grove &amp; Water Street) highlighted\" class=\"wp-image-19266\" srcset=\"https:\/\/i0.wp.com\/historyofparliament.com\/wp-content\/uploads\/2025\/12\/4613065-Arrowsmith-1842-Map.jpg?resize=1024%2C721&amp;ssl=1 1024w, https:\/\/i0.wp.com\/historyofparliament.com\/wp-content\/uploads\/2025\/12\/4613065-Arrowsmith-1842-Map.jpg?resize=300%2C211&amp;ssl=1 300w, https:\/\/i0.wp.com\/historyofparliament.com\/wp-content\/uploads\/2025\/12\/4613065-Arrowsmith-1842-Map.jpg?resize=768%2C541&amp;ssl=1 768w, https:\/\/i0.wp.com\/historyofparliament.com\/wp-content\/uploads\/2025\/12\/4613065-Arrowsmith-1842-Map.jpg?resize=1536%2C1081&amp;ssl=1 1536w, https:\/\/i0.wp.com\/historyofparliament.com\/wp-content\/uploads\/2025\/12\/4613065-Arrowsmith-1842-Map.jpg?resize=2048%2C1442&amp;ssl=1 2048w, https:\/\/i0.wp.com\/historyofparliament.com\/wp-content\/uploads\/2025\/12\/4613065-Arrowsmith-1842-Map.jpg?resize=1200%2C845&amp;ssl=1 1200w, https:\/\/i0.wp.com\/historyofparliament.com\/wp-content\/uploads\/2025\/12\/4613065-Arrowsmith-1842-Map.jpg?resize=128%2C90&amp;ssl=1 128w, https:\/\/i0.wp.com\/historyofparliament.com\/wp-content\/uploads\/2025\/12\/4613065-Arrowsmith-1842-Map.jpg?w=1440&amp;ssl=1 1440w, https:\/\/i0.wp.com\/historyofparliament.com\/wp-content\/uploads\/2025\/12\/4613065-Arrowsmith-1842-Map.jpg?w=2160&amp;ssl=1 2160w\" sizes=\"auto, (max-width: 720px) 100vw, 720px\" \/><\/a><figcaption class=\"wp-element-caption\">Locations of Coffee Grove, Caledonia and Water Street  on a composite 1842 map of British Guiana.

By 1815 he had made sufficient income to become a co-owner of the estates and a partner (with a 5% stake) in McInroy, Sandbach &amp; Co. He sold out of McInroy, Sandbach &amp; Co. in 1821, when his 5% share was worth at least \u00a312,500, but continued to own Coffee Grove &amp; Caledonia until at least the late 1830s. In 1829 his 50% stake in these plantations (his co-owner was Samuel Sandbach) was valued at \u00a331,200 (for more on calculating wealth in modern terms see below).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Outside of plantation management on the Essequibo coast, McLagan senior lived in the elite Kingstown district of Georgetown from at least 1814, probably at a property he owned on Water Street. A Presbyterian, in 1815 he was a founding committee member and benefactor of St Andrew&#8217;s Kirk, Georgetown. Two years later he purchased a second Georgetown property in the Cummingsburg district.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Although he did not marry until his return to the UK, McLagan senior was the father of two sons born in Demerara, John (1821-1850) and Peter junior (1823-1900). The latter served as MP for Linlithgowshire between 1865 and 1893, and a number of <a href=\"https:\/\/historyofparliament.com\/2025\/06\/12\/peter-mclagan-scotlands-first-black-mp\/\">contemporary sources indicate he was of African or Caribbean heritage<\/a>.&nbsp;No formal record identifying either boy\u2019s mother has yet been discovered. However, between 1820 and 1823, McLagan senior purchased a Barbadian-born enslaved woman named Filly and her three children (Henrietta, Joe and Robert) from another domestic residence in Georgetown.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Filly and her children were enslaved at McLagan\u2019s senior\u2019s Water Street residence between 1820 and 1823, where they continued to live until at least August 1834. Filly, whose story I\u2019ll explore in the next article in this series, may have been John and Peter\u2019s mother, or possibly their wet nurse. Alternatively, the timing of her sale to McLagan senior, and the birth of his two sons, may have been a coincidence. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">McLagan senior left Demerara with his two sons John and Peter in June 1825 on board the <em>Boode<\/em>. The boat, which was owned by McInroy, Sandbach &amp; Co., was loaded with an extensive cargo of sugar, rum, cotton, coffee and \u2018one pipe\u2019 of madeira wine. McLagan senior and his children arrived in Liverpool in August 1825, following which they lived between Perth and Edinburgh. In 1827 McLagan senior married Elizabeth Hagart Steuart. The family subsequently moved to 77 Great King Street, Edinburgh. Elizabeth died in November 1833.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large has-lightbox\"><a href=\"https:\/\/maps.app.goo.gl\/wLRMrWnfFcjFoZqy8\" target=\"_blank\" rel=\" noreferrer noopener\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"720\" height=\"476\" data-attachment-id=\"19277\" data-permalink=\"https:\/\/historyofparliament.com\/2025\/12\/11\/peter-mclagan-senior-1774-1860\/77-great-king-st-google-maps\/\" data-orig-file=\"https:\/\/i0.wp.com\/historyofparliament.com\/wp-content\/uploads\/2025\/12\/77-Great-King-St-Google-Maps.png?fit=1153%2C762&amp;ssl=1\" data-orig-size=\"1153,762\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"77-Great-King-St-Google-Maps\" data-image-description=\"\" data-image-caption=\"\" data-medium-file=\"https:\/\/i0.wp.com\/historyofparliament.com\/wp-content\/uploads\/2025\/12\/77-Great-King-St-Google-Maps.png?fit=300%2C198&amp;ssl=1\" data-large-file=\"https:\/\/i0.wp.com\/historyofparliament.com\/wp-content\/uploads\/2025\/12\/77-Great-King-St-Google-Maps.png?fit=720%2C476&amp;ssl=1\" src=\"https:\/\/i0.wp.com\/historyofparliament.com\/wp-content\/uploads\/2025\/12\/77-Great-King-St-Google-Maps.png?resize=720%2C476&#038;ssl=1\" alt=\"A row of terraced houses with cars outside\" class=\"wp-image-19277\" srcset=\"https:\/\/i0.wp.com\/historyofparliament.com\/wp-content\/uploads\/2025\/12\/77-Great-King-St-Google-Maps.png?resize=1024%2C677&amp;ssl=1 1024w, https:\/\/i0.wp.com\/historyofparliament.com\/wp-content\/uploads\/2025\/12\/77-Great-King-St-Google-Maps.png?resize=300%2C198&amp;ssl=1 300w, https:\/\/i0.wp.com\/historyofparliament.com\/wp-content\/uploads\/2025\/12\/77-Great-King-St-Google-Maps.png?resize=768%2C508&amp;ssl=1 768w, https:\/\/i0.wp.com\/historyofparliament.com\/wp-content\/uploads\/2025\/12\/77-Great-King-St-Google-Maps.png?resize=136%2C90&amp;ssl=1 136w, https:\/\/i0.wp.com\/historyofparliament.com\/wp-content\/uploads\/2025\/12\/77-Great-King-St-Google-Maps.png?w=1153&amp;ssl=1 1153w\" sizes=\"auto, (max-width: 720px) 100vw, 720px\" \/><\/a><figcaption class=\"wp-element-caption\"><a href=\"https:\/\/maps.app.goo.gl\/wLRMrWnfFcjFoZqy8\" target=\"_blank\" rel=\"noopener\">Google Maps<\/a> view of 77 Great King Street, Edinburgh <\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Over the following three decades McLagan senior played a limited role in Scottish public life.

However, in a subsequent interview, Peter McLagan junior claimed that his father had been \u2018worth \u00a3100,000\u2019 at his death. While this may have been a retrospective embellishment, it is in keeping with McLagan junior\u2019s own place in Britain\u2019s \u2018Upper 10,000\u2019 by the 1870s.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If McLagan senior had died with an estate worth around \u00a3100,000 in 1860 it would have comfortably made him one of the richest 10,000 people in the UK, and one of the 1,000 richest people in Scotland.
