This is great information! I did know that Ana Margrethewas born out of wedlock. I am thinking I got that information from church records. It is very interesting to see the census records of her father. I have done no research on him.
I do have the census records for 1885, 1890, 1901, and 1911, but none going back further. It was very interesting to see Soren's connection to the military not long before they were married.
I do have an address on the letters, but can't manage to pull any census records up after 1911. The address appears to be street names. I will scan them and see what you think.
