Hi Jean:
I have responded via email to you but for the benefit of other Gelling researchers I have reproduced part of that email:
"I have been looking back in my records re JG will and it seems I must apologise as the will I meant to refer to is by Margaret Quilliam b. 1740 Marown who married John Gelling b. 1740 Braddan. The will is actually the one of Margaret who died in 1822. I did submit this to be included on BL's DB and it is in fact on there ref: 0106423. JG b 1764 s/o abovementioned JG was left "the sum of three pounds British". There are other children of JG and MQ who are also mentioned
Sorry if I have misled anyone on this.
