Hi,
My 4th gt -grandmother was Jean Walker (1749 - ) of Slamannan, Stirlingshire.
She was the youngest of six children of John Walker and Jannet Gray.
Her Walker siblings were: James (1736 -), Jannet (1738 - ), John (1740 -), Henry (1743) and Thomas (1745 - ).
John Walker and Jannet Gray married at Slamannan on 6/4/1733. Jean's brother, John Walker, was baptised at Slamannan on 30th July 1740. It was witnessed by James Walker, whom, I should think, was either an uncle or grandfather.
John married Elizabeth Henderson at Falkirk in 1770. They had 4 children: Mary, John, James and Jean.
So, it would seem likely that the father of John Walker, who married Jannet Gray in 1733, was either a John Walker, or a James Walker, probably born at Slamannan.
There are several possibilities, from looking at Scotland's People, none of which are completely satisfactory.
Any help in this matter would be much appreciated, please.
Kind regards,
Gordon
