Hi Sue,

Not used to working in the 1600s too much!! I did mean 1690 - date comes from burial register which shows him aged 97.

German burials
1787 Patrick Kelly, Ballidge, buried March 4th, 97

his will -
Patrick Kelly 1787

Patrick Kelly of Ballalig German
son Patrick
dau Elizabeth
dau Jane
wife Mary als Crellin als Clague

here is Margaret Kelly als Crellin's will (his 1st wife)

1767 E1
Gl715
Margaret Kelly als Crellin d 21/1/last intestate
intelligence 3 daus
Margaret
Elizabeth
Jane
Patrick Kelly intestates only son having beem provided for by mariage contract

Patr Quayle husband of Margaret
Willm Kneale husband of Elizth
Wm Karran husband of Jane

pledges
Patr Kelly Kneeb
Henry Mylchreest
both of German

Patr Kelly the widower

Therefore Patrick is an only son and cannot be brother of 'your' John.

From Manx Notebook-
German will summaries (these could be the parents of 'your' John)

1782 A 35 KELLY Ann cretney d 30 nov 1781;eary coayn?;husb patk exor;son wm(heir),john,patk,philip;dau margt(w/o henry cottier),cath(w/o wm kelly);gdau ann kelly

So which Patrick (if either) is the son of Gilbert Kelly & Isabel Boddagh remains unclear.

Good luck!
Carol
