About us

Welcome to the O'Rourke surname study page on Family Tree DNA.

My name is Michael Cassara and I'm a genealogist living in New York City.  My O'Rourke ancestor is Hugh O'Rourke, born 1851 in Aberdeen, Scotland, to Irish parents.  

We are actively seeking new participants and are eager to have any male with the O'Rourke surname take a Y-37 (or higher) DNA test (our preference is Y-67, whenever possible).  Please contact me if you'd like to discuss this further, have questions, or would like to exchange information on the O'Rourke family.
