Pierce and Patrick Clear are related to each other. They may also be related to our James Thomas Clare Sr. If they are related their father will be either James or William. -------------------------------------------------UPDATE : Pierce, Patrick and James Thomas Clare Sr. are brothers. After discovering that the cm at Gedmatch could be changed from 7cm to 3cm I found 3 8th cousins who confirmed that the brothers were in fact brothers because of DNA results. I also found that the father was William Clare and mother was Mary Frances O'Neil. ---------------------------------------------------------Additional information. There is a Thomas Clare and Esther (Essy) Sheridan family that somehow are related by DNA. This Thomas may be a uncle of Pierce, Patrick and James Sr.. More research needs to be done.
