Hi
Can I please recommend you adopt normal nomenclature for describing ancestors. "Dad's dad" is grandfather etc....it makes life easier when trying to calculate the relationships.....It's very easy to misinterpret the written word regarding ancestry if it isn't made 100% clear who is being referred to.
Was your grandmother married to James Pick born 1918 as he is the issue of James Pick and Isabella Porteous Scobie?
Isabella was married twice according to most records I have sighted. She married Alexander Wallace and James Pick. She had a dughter idsabella Porteous but it is isn't clear who the father was, either James Pick or Alexander Wallace.
Scotlands people record:
Isabella Porteous Pick born 1922 Grangemouth, Stirlingshire, Scotland. GROS 481/B2 0206
She is ALSO recorded as Elizabeth Porteous Scobie on the birth record above.
RE: The Winton family. This is very well documented and Margaret Winton's Ancestry is recorded online going back at least 6 generations.
Her husbands ancestry is very difficult to expand as to date there is nothing that identifies which John Scobie he is. There were numerous John Scobies around at the time. The Scobie name is very prevalent in Perthshire from Perth down to Dunblane and most places in between. A large contingent is documented at
