Dont know if there is any connection here at all but am researching Kilday/Kildea in my family tree. My Greatgrandfather was Thomas Kilday, born in Donegal,Ire. circa 1835. He married Susan McFadden (also of Donegal Ire.)He immigrated to US;either NY or Philly. Was in the 100th PA volunteers in the civil war serving from 1861-1865; wound at siege of Petersburg VA. Likely immigrated between 1858-1859; lived in Philly. One possible brother in Philly was a James A Kilday(married Margaret McFarland). Children of Thomas Kilday and Susan McFadden (all born in Philly)included Charles(1860), Thomas (1865), James1867), Joseph (unknown), John (1871), Francis Miles (1872)Mary (1874), Anna (1877) (my grandmother).
