In the Will of William Casement of the Kelley (presumably the Kella nowadays) Lezayre, made on 22 April 1699, William Casement refers to his sister Margaret and sister Grace, and to "my father William Crow" and later on to his brother Charles Crowe and his sister Margery Crowe.

I assume from this that the modern use of "in-law" to distinguish the spouse's father and siblings was not necessarily in use at the time, so that his father "William Crowe" was what we would term father-in-law, and was therefore the father of his wife Elizabeth. The brother Charles Crowe would be a brother in law.

Can anyone confirm that I am correct in this assumption. Brew implies a line Thomas Casement who was MHK in 1662 directly to William who married Mary Thomason in 1719 (but omits the marriage to Jane Knipe als Wattleworth in 1708. The Casement family later occupied the Kella, and my guess is that the William who died in 1699 is an intermediate generation, and the time would ertainly permit this. He left a wife and 5 children, the eldest being William. I believe it is this William who married Jane Knipe.

Does anyone have any corroboration on this.
The 1699 will also refers to a Thomas Casement who died some 27 years earlier ie x1673, so I think he is the guy who was the MHK in 1662.

Based on these wills, the conjectural tree at present is

1) Thomas Casement - date of death ?

2) Thomas Casement MHK in 1662, died c 1673

3) William Casement d 1699, m Elizabeth Crow(e) had following issue, William. Elizabeth, Cathrin, Margaret and Thomas. Wm being under 21 when his father died in 1699, and the rest under 14.

4) William born some time c1680, and referred to as under 21 in the 1699 will m Jane Knipe in 1708, m Mary Thomason in 1719 and later on m Dorothy Parr, als Humphrey, and died in 1733.

5 Ewan or Hugh Casement born 1720
---------------

At present that is conjecture, so can anybody help firm that up ?
