I hope you may be able to help me. I am researching a Frank Gallagher who was born ca 1848 in Pennsylvania and died in McKeesport, PA in 1920. His wife is named Margaret who was born in Ireland ca 1849 and they were married in 1875.
Children: all born either in Pittsburgh or McKeesport, PA
Mary b. 1876
Margaret b. 1879
Katherine b. 1881
Hannah b. 1883
Sarah b. 1888
I have had little success tracing him before 1880 and was hoping you may have information on him. I have been researching the descendants of his daughter Katherine.
