Thank you, Bo. I have listed as Per Erik's parents: Erik Bill (b. 1785, d. 1848 at Norra Martenstugan, Backstuga) and Anna Stina Persdotter (b. 04 May 1794, d. 11 Apr 1858 at Norra Martenstuga, Backstuga). This info came from another family tree I found, so is not verified.
Catharina Charlotta's information you found corresponds with my records!
