I am trying to connect these two Rivett/Revett cousins or possibly brothers.
I believe the surname spelling changed to Revett when James Rivett emmigrated to the USA in 1824, to New York, then later to settle in DeKalb County, Indiana. John Rivett remained in England.
John Rivett was the father of a Mary Jane Rivett (b.1859 in Wimblington, Cambridgeshire) who is directly in my tree. I believe Mary Jane's mother was a Frances Hudson (Machin). John may have had a previous wife (Susan Nash) and family, they were possibly married in 1838.
James's parents were James Revett and Abigail Knight. I cannot link John to these parents, at least not yet.
Thanks
Mike
ps I would be happy to provide more information if required.
Mary Jane Rivett is the mother in the photo to the left.
