Thomas Gilbert of Yardley, Thomas Gilbert, of Wethersfield is listed as having been born: April 25, 1589.
His mother is listed as being Margery (Morken) Gilbert, Margery Gilbert with a death date of June 25, 1575 , almost fourteen years BEFORE Thomas' birth. (This fact is pointed out as an inconsistency on Thomas' profile). Something is wrong here in the data: either Thomas had a different mother than Margery, (or his (Thomas's) birth date is incorrect), or the death date for his mother, Margery is incorrect and needs correcting.
