This is a One Name Study to collect together in one place everything about the surname Costello and its variants. The hope is that other Costello researchers like you will join our study to help make it a valuable reference point for people studying lines that cross or intersect.

Work to encourage Costello descendants that would like to join the YDNA project. Identify common Costello ancestors.
