Does anyone research the DAVIDSON family of Wilkes Barre? I just received a picture of what looks like 4 generations taken about 1912: baby is Ruth RALSTON JONES, her mother is Abi DANN RALSTON, Grandmother is Alice KNOTT DANN (born 1866 in England, father John KNOTT), Greatgrandmother(?) is identified as Grandma DAVIDSON. Anyone with any info on these families please contact me. Thanks! Connie
