I've got one in my family.
Levi MELLER married Paye Ettl LEVIN (1870?). He took her last name.
Story goes that Paye had no brothers, Levi became the "only son" and head of the family, avoids conscription.
I can't find any records of them (not sure where they were born, where they married, last names are not distinctive enough).
They ended up in Yekaterinoslav (Dnipro) maybe, some indication that they may have been from Lithuania.
A bit of a mess, genealogically speaking.
Their grandson Lewis used Meller as his middle name on his naturalization papers.
