I have some info on my family tree (I'm not a blood relative though) The Beerli line I have starts with Otto Oscar Beerli 1887-1945. He was a baker, born in Switzerland, and first appears in the 1911 census at age 24. He married Bessie Violet Seward Stuhldreer in 1913 in Bethnal Green. They had 5 children that I have found: The main 2 are: Otto Paul Anton Beerli 1914 (known as Paul)and Derek Paul O Beerli 1929-1985. The other 3 children Eric, and twins Eleanor & Violet died soon after birth.
Derek married Eileen Manz in 1951 and they had a daughter Lesley in 1954.
Otto (Paul) appears to have married twice. First to Dorothy Frances Dryden in 1939. They had a son, John A Beerli in 1945. I believe they may have divorced, as he married Isabel McKimmie in 1951, but Dorothy died in 1990 in Cheshire, her surname on the death entry was shown as Beerli, and their son married in Birkenhead, Cheshire.
