According to the 1910 Alaska census Harriett states b Ireland, emi 1885, if fact, you won't find them on a NY census, unless there is a state census 1885/1895. The last I find of Rebba....1907 San Francisco Directory. She and Harriett both 1900 San Francisco census; teachers. They both state b NY, but it doesn't match the AK census. Didn't find them on passenger list. Maybe someone else will have better luck.
