Sue - We have a similar problem on the Kelly lineage where John Kelly of Ballabrew, Baldwin in the parish of Braddan married a Jane Christian. (c. 1680's) Their son & heir Robert Kelly I m. Margaret Christian of the Flatt, Maughold, but despite looking for 30 years I have no idea who Jane was. She mentions someone in Andreas in her will, and her daughter in law's identity suggests a northside link.
