Exactly 110 yrs ago today (July 30, 1900), my ancestor Mayer Mahler became a US citizen.
Mayer married his wife, Tillie, and had 2 children in Russia before leaving the Kovno region (see above map, now Kaunus, Lithuania) to arrive in America in 1885. He renounced his citizenship as a subject of the Emperor of Russia, and with Adam Adler as his reference, became a new US citizen in 1900. Tillie and Mayer had 5 more children in America, where he lived for 25 years before his early death. His wife Tillie lived to be 99 years old!
