There is a photo of the tombstone of James Eugene Callow on Debbie DeRenard's site. Her e-mail address is DDrenard@aol.com
James E Callow is descended from the Ballaterson East Callow family of Maughold. (See History of Kk Maughold by William and Constance Radcliffe).
I notified Debbie DeRenard about this connection some time ago but haven't heard from her since.

Frank B Callow the last surviving male Callow of this line died at Parma Heights, Ohio this year. He wrote a book about the history of his family but I haven't seen it. You would probably have to contact a relative to get a copy.

There are also data pertaining to this family on Clive Callow's Gedcom files but you need a descendency chart of the family in order to differentiate them from 9 or 10 other Maughold parish Callow families that are on this Gedcom file and which are described briefly in Radcliffe's' book.

There is no proveable connection in my direct Callow line with any of the Maughold Callow families and therefore with the family you are trying to research.
Let me know if you can't contact contact Debbie DeRenard and I will pass on what I know about this family which was researched in some detail by the Radcliffe's back to the late 17th century. Much of the information pertaining to younger siblings of each generation of the Ballaterson Callows was not included in their book
but is available to those who are doing active research.
