Lynne, thank you for the will reference for Paul Gelling 1736.
Richard Gelling of Knocketrodden Braddan is Paul's son-in-law. He was married to Paul's daughter Elinor. Richard (1707-1788) is the son of Capt. Paul Gelling (d 1732/3) & Elinor Taubman. I don't know if they were related, but they probably were.
Paul Gelling & Ellinor Oates of Camlork had 3 children: John (1702-1788, md Catharine Kelly 1726), Margaret (1705-1736, md John Cubbon 1726), & Elinor 1710-1789, md Richard Gelling abt 1731). The articles of agreement upon Paul's death 1736 were between son John & son-in-law Richard. Only other child Margaret died shortly before her father. Paul's wife Elinor Oates was buried 16 Oct 1710 Braddan.
The 1726 marriage contract of son John Gellin & Kath Kelly between parents Paul Gelling of Camlork Braddan obo son & heir John, and Ann Kelly als Cannell (Ballavargher Marown + intended wife of Paul Gelling) obo dau Cath Kelly indicates that the two widowed parents are about to marry each other. Paul's last wife Ann Cannell (deceased) is mentioned in his will.
Ann Cannell's first husband was John Kelly (md 17 Nov 1702 Onchan) and their daughter was the Catherine Kelly in the above marriage.
It would appear that Paul Gelling of Camlork didn't marry anybody after first wife Elinor Oates died 1710 and before marrying Ann Kelly als Cannell abt 1727. Ann was buried 8 Sep 1733 and there is a will for her that matches well.
Paul's first wife Elinor's father was Capt John Oates and he died 1727. His will mentions Margaret & Eleanor daughters of Paul Gelling.
All this is enough to spin anybody's head.
