Hi. Just wanted to check on this profile. My Great grandmother's name was Liba Sliwka Liba Rozenblum born in 1877. I also found a JRI record of a Liba Sliwka born in 1877, without the parents listed, I made the assumption that the birthday listed in that record was the correct date, since we know she was born in 1877. Since there's another Liba Sliwka here born in 1877, just wanted to know what your source is for this profile.
