Looking for any information on the descendents/ancestors of Patrick (O')Rourke and Mary Lawlor based on my research they were born around the late 1840's.They had the following children:

Mary O'Rourke ( b. 1873 Ardfert d. 1940 Buffalo, NY)
Timothy O'Rourke ( b. 1871 Ardfert d. abt 1920 Buffalo, NY)
Hanoran (Bridget) O'Rourke ( b. 1873 Ardfert d. 1899 Buffalo, NY)

I believe there are other children.

Any information would be greatly appreciated.
