I amlooking for information on a Bertha Radtke born in Wisconsin in 1893. she had a brother named August. I don't know if it was an older or younger brother. Am still gathering information, but interesting coincidence. So close in name and area. Have you come across a Bertha? She married a Carl/Charles Helsinger and died in 1972. She is buried at Highland Memorial Cemetary near New Berlin, Wi. I have sent for death certificate in hopes of gaining more info.
