My ggg grandfather was the John Bruce you have named, born 13 Mar. 1774 at Archballoch, Alford, Aberdeenshire, North Britain(Scotland). John had a brother, William, b. 30 June 1776, Archballoch, Alford, Aberdeenshire, North Britain, and a son, William, born 6 Nov. 1803, Malew (not the William you have quoted). I have questions too about the William buried at Andreas and Margaret buried under John's headstone. Please email me at brucefamily@shaw.ca if you wish to discuss further.
