GenesReunited has come up trumps again. A while ago I found another FAIRBAIRN twig had married a FOTHERINGHAM from the Orkneys. And there she was on GR. The descendant (Diana) has now been in touch, extending the family of James and Agnes down to present day (Hampshire mainly).
In the process of getting John, son of James and Joan (FORSYTH) FAIRBAIRN onto the web as Melinda has come up with a couple of photos and some family snippets that illustrate the relationship evidence.
