On my maternal grandmother's  marriage certificate, she listed her mother's maiden name as RUBIN. She may have been confused because her mother's maiden name was definitely REICHMAN/RAJCHMAN (or alternate spelling version of this name).
She also told me that she (Gittel/Gus/Gertrude MICHALOWICZ aka LEVINE & SCHULTZ) was named for her grandmother (actual first name presently unknown). Her two sisters' daughters (her nieces) also were named Gus/Gussie, assumedly in honor of the same person.)
My grandmother's paternal grandmother was quite probably Gittel. However, she is listed on JRI-Poland as "Gittel ZOLNA/ZOLNY", not RUBIN. I know that the name RUBIN is part of my family because I have a few photos labeled Harry & Fannie RUBIN & children, relationship w/i family presently unknown. Because Gittel ZOLNA was probably born in the first quarter of the 19th C. Could this be another case of "dynamic" or "fluid" (as opposed to permanent) last names?? (The family mainly lived in Lodz/Tomaszow Mazowiecki)
