Hello, I'm an O'Brassill descended from GGF Joseph Brassill (changed to O'Brassill), whose father was Dennis Brassill married to Mary Neligan, whose father was also Dennis Brassill, married to Bridget Quinn, of Ireland. I have no further information than this, but would be very interested in hearing from anyone who may also be seeking the same family members, or have any other surname information. Thanks so much!
