I am looking for information about the family of my grandmother SARAH MCELHATTON HANRAHAN. Sarah came to Philadelphia, Pennsylvania USA from County Tyrone prior to 1906. She married John HANRAHAN in Philadelphia in 1906. According to Sarah's death certificate, her father's name was JOHN MCELHATTON. Sarah also had brothers named PATRICK and WILLIE and a sister named MARGARET. All clues are most gratefully accepted. Thank you!
