Mr. Callow; I consider you the Icon of Callow Genealogy and I am very happy that you responded. Regarding Anthony Callow, I have basically followed the tree of Cheska Wheatley. She listed, without a source, the fact that Anthony was buried in IOM. While most of her data has been right on I do get worried without a good source.
I have recently made contact with a new lady who claims to have an old Callow Family bible and also "thinks" that there may be some link to Anthony and IOM. I should get her data this month and will investigate.
In addition, I have another dead end on my wife's side of the tree with her Great Grandmother Olga Petrea Semina (1845-1890), who is reported to have been born somewhere in the IOM. I have some decent data on her husband Per Mannson (1834-1890), but can't find much on Olga.
