The Mayper Family
Including the Saydmans, and parts of related families such as the Romms, the Chipkins, the Leveys, the Avramsons, the Bayers, and several others.
The name Mayper is unique. The family members all descend from the first Maypers, Avraham Naftali Mayper and his wife Gela. Avraham Naftali Mayper was born about 1790, probably in Rumshishok (Rumsiskes), Lithuania, then a part of Czarist Russia. He and Gela had a daughter and three sons (as far as we know now - could be more), Perlina, Ben-Zion, Ephraim, and Mordechai (Marx). The family lived in Rumshishok until the late 19th century, when many emigrated to America and other places. Today, there are Maypers all over the United States and in several other countries.
The Saydmans are on the direct Mayper family line. One of Avraham Naftali's grandsons changed his name to Saydman on the way to America, because of pressure from the Czar's army conscription agents.
