okay some information must be fixed here
her full Name was: Mamchi Esther Gittel
Maiden family name: unknown
she is buried in Kolbosowa
Lived: (circa 1842-1925), her son Mendel was born 1861 so she was born about 1842, also the tradition in the family is that she lived long, she died (כ"ג אייר תרפ"ה) May 17 1925 and if born c. 1842 she was 83
her fathers name: Yehuda Leibush (not Leib)
on gravestone says: she was daughter of הרבני R' Yehuda Leibush grandson of Rabbi Elimelech of Lyzensk...
I personally did a lot of research to find the connection (also DNA) but so far didn't find any (have some Dna relation to others with a connection), the biggest speculation is that Yehuda Leibush may be rabbi Yehuda Leibush Wolkenfeld, and his date of birth given in מליצי אש is not correct
if we may find the her maiden name it may help to verify it, the only place where i think we may still find something is in Germany where her son Menachem Mendel Lived (died in Berlin Feb 28 1939), so far I was able to get his death records, but it did not give this information, but there may still be other sources where to find other document with more details, I hope maybe one day one of the experts will came up with a solution
