Hello, My Riggans are mostly(so far) only in Pa. Here's what I have:
George Riggans ( born 7/1885)
Howard Riggans ( born 6/11/1887, died 7/25/1970)
Albert Riggans ( born 6/5/1889, died 4/7/1971)
Stewart Riggans ( born 4/26/1892, died 4/5/1960) - my great-grandfather
Clara Riggans (born and died unknown) She married someone named Ringer. Had 2 children: Harry Franklin (born 2/21/1908, died 10/12/1981 in LA, Ca.) and Virginia Lauretta. She lived some time in Ohio then moved to California.
There are also many spelling variations on this name but my family spells it with the "A". Any information would be greatly appreciated!
