Hello Jeanette
My known Boags start with William b1801 Abercorn who married Elizabeth Robinson 09 Jun 1821, Ecclesmachan, she died 1840. They had family - James b 1822, John 1826-1831, Mary b 1828, William b 1829, Catherine 1833-1901, Male Boag 1836-1836, and Elizabeth b 1836. William then married Margaret Colbert 08 Nov 1840, in Abercorn, and they had family - Betsy b 1843, Agnes Nimmo 1847-1923, and Charles b 1848. William died 18 Sept 1872 in Abercorn, and Margaret died in 1889.
Wlliam's daughter Catherine married a James Wallace 22 Apr 1857 and they emigrated to Canada.
I have very little experience with Scots family, and I haven't managed to find William's parents at this stage.
