My ggrandfather was Wolf Berek Bajer born in Nadarzyn, Poland in 1842. His father was Aron Bejar and his mother Blima Szelinger. When my ggrandfather married Sura Fajga Anielwicz from Mogielnica, his name was recorded as Wolf Ber Beker. Wolf Ber married a second time in 1891 to Ruchla Fuks. They had 3 children that I know of. Cypa (f) and Szymon(m) in 1892 and Szmul in 1894. Szymon Beker became Samuel Becker (my grandfather) in America. Szmul Beker never came to America and asfaras I know perished in the Shoah. Samuel and Szmul had a fight and stoppped writing eachother in the 1930s sometime. Hop;e this helps.
