Hello John, I looked up your GM's wedding record in Brookline in 1906, because I also have a Thomas Keane (b. 1876) whose mother's family also married the Conveys, and I thought isn't that a coincidence. But your Thomas Keane's parents were William Keane and Sarah Kelley, my Thomas' parents were Martin Keane and Catherine Mulligan. Catherine and Martin married in Killasser Parish in County Mayo on 21 Jan 1876. Do you know where your Thomas is from?
Have you looked at the church records for Cully? I wonder if you can tie your James Phillips in to the other Phillips I listed in my post above.
Thanks for writing!
