Send a message to the person who requested a photo of the grave monument of James March with the following comment:
As a matter of family history- my g4 grandparents were a Robert Linton and Elizabeth Allan who I am researching. Their son (my ancestor) migrated to Australia in the early 1800s and little information has been passed down on the happenings of those left in the old country. This may provide the link if I can work out the relationship of the people named on the headstone.
