I am desperately looking for information on the following people, my great grandparents:
Otto Belnhalt Priess - 1/1/1880, Barenfels Saxony. May have a sister named Martha, do not know anything other than his birthdate and that he immigrated to USA in 1907.
Martha Kaiser - 9/17/1878, Altenberg (broad, sorry). Do not know parent's names, immigrated to USA in 1907 with Otto Preiss as husband.
Also searching for Eleanor Stoess/Stoss - born 3/2/1870 in Elbing. Has twin sister Elizabeth and other siblings including a Caroline and Emily. I don't know parents names, or anything specific.
I know Saxony archives aren't quite online anywhere and I've exhausted all my known sources at ancestry, familysearch, Archion, and here. Can anyone help? Any advice?
Please and thank you!
