I have documented my KREINDLER line back to my GG Grandfather, Simon Kreindler, who was born in 1790 in Solotwina, a shtetl in the Austro-Hungarian Empire not far from Stanislawow (today it is Ivano-Frankivsk, Ukraine).
Although the KREINDLER name is not all that common, I have never been able to connect my line with the KREINDLERS of Club 21 fame. Their earliest ancestor in the US was Kieve/Carl KREINDLER who arrived in NY either in 1900 (according to Ellis Island records) or in 1896 (according to his son, Peter).
Kieve/Carl’s branch subsequently changed the spelling of their name to KRIENDLER, probably because it was grammatically more correct in English-speaking USA. My line retained the original spelling.
Years ago, I tried to find out where Kieve/Carl’s family had originated. It was not on his Ellis Island arrival record and none of his family apparently knew the answer (although the ones I spoke to were also very curious).
I wonder if, in the intervening 20 plus years, any of the KRIENDLER branch has been able to find the answer? If so, I would be delighted to hear from you.
