Hello Ceeoh
Wow!! I can't quite digest it all, but if all these folk are having difficulty linking relationships among Burnsides, what hope have we got of fitting in a Smith?
I did just wonder, if Mary was from a family of travelers/ tinkers, how likely is it that she would marry outside of the traveling community?
We know a lot about Charles Grout's background and it is much more conventional. He came from Loughton Essex, where the family remained. There is an unproven family story that he fled to escape charges for poaching in Epping Forest. His father was a publican and owned land and property and left a fairly substantial legacy, but divided many ways. Charles and some of his family benefited from the will, so contact with the family appears to have been maintained. Charles was literate.
What is SKS?
