According to the family bible of Francis McBrearty and Elizabeth Jameson, Patrick was born in s. Heberton, Pa on March 31,1877. There are ww1 draft records for someone with his birthdate according to Sacramento County, Ca rolls. I also found a marriage listed for him to Marie M cClary in Classen, Ca on August 1'1922. His parents are listed as Francis McBrearty and Elizabeth Jameson, my great grandparents.
He died in Sacramento on May 1, 1938.
The family bible also tracks the family from Penn to Missouri in August, 1877, and to Texas ( Palestine, Taylor, and San Antonio).
