Hi all - Just went through my files and have the following.
Elizabeth Bayne Stewart, was sister in law to my g/grand Aunt, if you can get your head around that

.
So -
Her parents were Robert Stewart 1849 and Janet McGregor 1849-1916.
Marr - 11 Dec 1868 GRO386/A0 0014 Muthill.
Parents of Robert as per marr cert are listed as JOHN Stewart and Jane McCulloch. Parents Janet Peter McGregor and Elizabeth Bayne.
Janet died 15 Apr 1916 Doune Mill Cottage GRO362/00 0013 informant Robert Stewart (husband).
Have no death for Roberrt..it states in the 1901 census he was born Cornton, Stirlingshire

but have not been able to prove this (as yet) on this census he is a cotton mill carter at Kincardine.
If you want any further info..get back to me and I will double check files..I have twelve children listed for Robert and Janet

All the best Patvp
