Sorry everyone I wasn't able to respond earlier re the WULFSON query and then this message was rejected by the gremlins!
One of my maternal GGGGF's was David Behr ARONIS b. ca.1800 d. ? He married Mahle/Malka bat Israel b.ca. 1898-1800, d. Libau 1862
They had several children, including my GGGF Leib/Levin ARONIS b.ca. 1833 (possibly Kuldgia) d. Libau 1901 and Salomon/Sholom ARONIS b.ca.1831-34 d. Libau 1869.
Salomon married Esther nee WULFSON b.ca.1848 in Libau in 1867.
Esther and Salomon ARONIS had one known child, Shimon-Beer ARONIS b.1868 Libau. Nothing further known about what happened to this branch of the family.
Sorry I do not know Esther nee WULFSON's Father's name.
