Birth/Walter Bone/Bet. 1782-1791

[Peggy13]

Walter's parents were William Bone and Marrion Sandilands.  they were married in Scotland and had the first 2 children there.  I suspect that they may have gone to England for a while and that Walter was born there.  They were back in Scotland by 1792 as David was born back in Scotland.  Family stories say that they are related to John Bone and Mary Talford who were from England.
Any information on Walter's birth greatly appreciated.  Walter went on to marry Mary Brown and that marriage cannot be found in Scotland, although all the children are born in Dumfries, Scotland.  The marriage would be about 1808.
Thanks for any help
