The 1613 date is actually Catern's baptismal date. She was baptized as Katheryn, I believe, but her great granddaughter was also called Catern, so her descendants generally refer to her by that name. The theory is that she was the daughter of Francis and Grace Jeacockes (Jaycock) of Stratford-upon-Avon, Warwickshire, England. The theory that Robert Ashman's wife was a Jeacockes derives in part from an unproven reference by Thomas Jaycocks to Robert Ashman as his brother-in-law. Some have taken this to mean that Thomas' wife, Ruth, was an Ashman. Others that they married sisters (I think that may be where the Armitage name comes in.) The problem is that early genealogists didn't provide full citations and transcripts, so it is necessary to backtrack. I feel that the birthdate for Thomas Flewelling of 1673 is a guess made years ago, and might well be wrong. Recent evidence has shown that the Thomas Flewelling who married Hannah Ashman was associated with Robert Ashman and Thomas Jaycocks as early as 1664. The concept that Thomas Flewelling, Sr. and Hannah Ashman died early, leaving one child, Thomas Flewelling, Jr., may have derived from one of my theories about 10 years ago. I am less sure of it, but there is still no evidence that they had more than the one child. They may have living in 1683, when Robert Ashman died, but it is likely they were dead by 1698, when Thomas Jr. appears in a census of Hempstead. The problem is an intriguing one, and may have a solution. One thing nobody has tried, as far as I know, is checking probate records in Stratford-upon-Avon. I doubt that Robert Ashman left any descendants of the name Ashman, but his other descendants are extremely numerous, and his given name, Robert, survived for at least 200 years amongst his decendants.
