Hi Annie... Already tried that, the normal pattern seems irregular in this family.
Children in descending order:
1st infant died, female, no name known, born act 1846;
2nd child, 1st son: Thomas Purvis (after paternal grandfather);
3rd child, 2nd son, Charles Watson Purvis (named after paternal grandmother's brother...a little weird, but this great uncle was influential in starting them all in the family pottery trade in Glasgow);
4th child, 2nd female, Margaret Purvis, after paternal grandmother... could be that Jane Lang also had a mother named Margaret, too...
5th child, 3rd son: James Watson Purvis, named after paternal grandmother's father;
6th child, 4th son: Robert Watson Purvis, Robert after his father, Watson again;
7th child, 3rd daughter: Emma Ann Purvis, named after a sister in law of father.
The only birth record I found for follows:
in Pollockshaw: Janet Graham Lang 1816 Volume 21, page 360. The record reads:
Archibald Lang writer and Elizabeth Graham LD Janet Graham bo 6th Augt. Wit: John Lang & Alexander Graham. ‘in Pollockshaw Glasgow’...
There are no other Jean, Jane, Janet Langs born about that time in Pollockshaws...
However, there are no children named after Archibalds, Elizabeths, Alexanders or Johns. I find that suspicious, which makes me wonder if this record is correct.
The 'Pollokshaws' location is in numerous census returns, etc. as her place of birth.
Stumped, and unwilling to completely trust this one record. I have been gnawing on this bone for years!
Thank you for your thoughts and ideas. Have you done a DNA test? Perhaps we might match, and that would be a clue...
Best,
Jean
