My name is Stewart Boa, I live in Florida and may be able to help you in your search for some possible answers.
My family originally came from Scotland. My family as I know it came from Roxburghshire, Scotland. The orig. BOA, as we know it at this point in time, was Andrew BOA born in 1761 and died 6 Aug. 1829 in Montreal, Quebec, Canada. His wife Agnes SMAILS, born 1760 in Roxburghshire, Scotland, died 20 March 1827 in Montreal, Quebec, Canada.
They had (9) children, Peter BOA (1786- ?),Ann BOA (1788-1838), Robert BOA (1790-1860), Andrew BOA (1794-1858) he is my great,great,great Grandfather, Janet BOA (1796-1857), William BOA (1800-1878), Margaret BOA (1802-1820), John BOA (1804- ?) and Agnes BOA (1806- ?).
All of the children, except Peter who stayed in Scotland, including the parents moved to Canada lived in and around the Montreal area.
The BOA'S you are interested in could be part of the same family of BOA'S but I would like some more info. if possible from you.
I would be willing to talk with you if you like.
Please submit an answer through e-mail to me.
In my search I wasn't able to find a Mary BOA and any info. on Janet Kathleen BOA born 1891.
Where did your original family settle after they left Scotland ?
Where do you live. Did any of your family live in Canada ?
