Be careful, I do have some Manx families with 2 living children with the SAME name. They tend to be pre-1750, though. One Keig line of my family, in Arbory, had 2 Catherine Kegg's, one born about 1701, and another born abt 1709 in Arbory, both children of William Kegg & Mariott Duccan of Arbory.. Also, I can't find find a link between this branch and the Rushen Keggs, any connection between is pre-1600.
