HI
Yes you have followed the same line of decent to Christopher Tatton who migrated to the Warwickshire area sometime between 1633 and 1640 I can give you information on that. He was born in the same town as myself Didsbury Manchester. I have a baptism for him in 1609 in the Tatton church at Northenden in 1609. The IGI for some reason has him as baptized in Didsbury St James around 1610 very strange. He later appears in the Didsbury Church register as father of a child Mary mother Elizabeth Davy but no evidence of a marriage. The child died 1 month later.
The most likely parents for Christopher are a Nicholas Tatton & Dorothy Linney who seemed to be the only Tattons using Didsbury St James for baptisms at that time. If that is correct then he would be the grandchild of Robert Tatton & Dorothy Booth From there the Tattons go back directly to another Robert Tatton in 1290.
Returning to Edward Tatton & Ann Bellamy we do share the same 4th Great Grandparents. From them my line goes to Henry Tatton & Mary Mills then to Henry Tatton & Emily Blizzard to John Henry Tatton & Laura Williams and then to John Tatton my grandfather. My mother was the Tatton so I do not have that surname.
I do not know how to get in contact, I do have a login for Genes Reunited but I have never published my tree and have not paid a subscription.
I have looked for you there but there are several Richard Tattons with the same date.
