brian mckay's family tree
I know about Jean from her daughter, Helen's birth record, see below. From that I was able to discover the record of her marriage to Robert Biggar, but that's it I'm afraid. There is no record of a Jean Thomson being born in Selkirkshire in what could be considered a reasonable span of time (1755 to 1775). There is also no sign of her in the 1841 or 1851 Censuses - not surprising perhaps, as she would likely have been over 70 at that time and probably deceased.
