OK, I’ve just gotta do this: :-)
My father’s oldest brother’s (FOB) completely hand-written 1890 Romanian birth-cert, showed the surname as BERCOVICI.
4 children and 15 years later, my father’s own printed-form, hand-filled 1905 birth-cert. from the same town as above also showed the surname as BERCOVICI.
My GF’s and my FOB and 2 other sibs on their ship’s Passenger List (PL) of June 1907 showed the surname as BERKOWICZ.
5 MONTHS LATER (Nov. 1907), on 2008 version of “FindMyPast.com”, my GM & 4 children were shown _leaving the UK_ on a different ship, landing at a different PoE and showed the name BERCOVITCH.
Same month (Nov., 1907) the above ship’s PL showed the surname of my GM & 4 children as BERCOWITCH.
Oct., 1910, my father’s older (NOT oldest) brother shown on N.Am. death cert. (written by a local Official) as BERCOVITCH; Signed by his father as BERCOVICH.
Later, Census A – Family name written as BERKOVITCH.
Census B – Family name written as BERCOVITCH.
Census C – Family name written as BERCOVICH.
Census D – Family name written as BEREOVITCH (and was _that_ tough to find!!).
1930s my father marries with name BERCOVICH, which has held for all family members since then! (with a couple of exceptions!).
All of the above fall into place with Peter COHEN's "Fri, 17 Jul 2020 14:41:41 EDT" message, but there _are_ a lot of spelling changes!
Cousin’s GF lands Ellis Island early 20th c. named on PL as GOLDSTEIN
Cousin’s GF & family listed on 1920 U.S. Census as GOLDSTEN
At a later date, the cousin’s father’s name was changed from GOLDSTEIN to GONSALVES
At an even later date, the cousin’s father’s name was changed from GONSALVES to GORDON
The last 2 changes were consciously made!
Note: ITEM 2 names have been changed to protect the innocent.
NONE OF THE CHANGES IN THE ABOVE TWO SETS WAS MADE BY FEDERAL GOVERNMENT OFFICIALS _AT_ THE PoE!
AND WE WON’T EVEN _TRY_ TO TRACK THE NAMES ON THE MATERNAL SIDE OF THE FAMILY (NO OFFICIAL GOV'T-MADE CHANGES THERE, EITHER) OR THE SPELLING OF THE GIVEN NAMES!!! :-)
Stay well, all!
