Records for Scotland on
https://www.scotlandspeople.gov.ukWALKER HENRY PETER WALKER/MARGARET CHALMERS 15/01/1792 Whitburn
I would guess below that this is the above Henry based on the naming pattern but do you know anything about Barbara?
HENRY WALKER & BARBARA MUIRHEAD had 3 children at Torphichen
Peter Grizel & Margaret
1826 – 1832 & Hugh & James 1835 – 1837 at Linlithgow
WALKER HENRY WILLIAM WALKER/ELIZABETH WHYTE 13/04/1796 Whitburn
Whitburn deaths pre 1855 are on SP but no record for Henry so both may have survived.
There are only two marriages in West Lothian for Henry Walker
BARBARA MUIRHEAD 6/04/
1828 West Calder
BARBARA WALKER 14/04/1828 Torphichen. (I do not see any children for this Barbara).
However this may be the same marriage and parish records would need to be checked.
