Frances,
I'm tied up for a couple of days but will get back to you on Taubman info. The material I have from John isn't computerized so I'll need to spend some time getting it to you. Essentially what I have is his fairly detailed outline of the Taubmans in IOM starting with Thomas Tubman @ 1480 from Cumberland.
I know that John's material is all from his perusal of Manx records while he lived on IOM.
