I've started a complete new thread as old one much too long.
1. what children/ grandchildren or other relatives are named in the will of
Bahee CORKILL, 1815 Maughold A 85 0106240.
Was her son William 1779-1833 married to Catherine Kelly with at least 6
children, and descendants around the world, or was Cath Kelly's husband
William Corkill 1779-1855 of Ballagorry Mooar? - will look up once I get back to Peel

2. Most important for Tony:
Ew Corkill & Ann Cashin contract no.18. Index page 4
- summary is on CD Rom - [rh + bottom margins decayed and partialy missing];dated 5 sep 1701;

Others that might help sort out the early families:
3. Dan Corkill & Margery Christian Contract 1676 no. 56 or 86. Index page 2
[which precedes your Old Mau **** 01 onwards, which starts at the bottom of
the filmed p.3].
Could this be Daniel Corkill & Margaret Karran marr. 2 Jun 1668?
