Sorry it has taken so long for me to reply. I have not worked on my research in a long time. The Peter Hagman I am referring to may have been the brother of Alexander Hagman. Alexander is my father-in-law's great grandfather. I am having a difficult time fitting together the pieces of this family tree due to the death of my mother-in law who had kept track of the family histories. My Peter Hagman had several brothers and sisters, but I do not know if his wife's name was Louisa. His siblings include: Alexander, David, Emma, Frederick, Harold, Ida, Katherine, and Margaret. I am honestly not sure if the ladies listed used Hagman as a maiden name or married ones. These may be husbands and wives. Anyway, I am not sure if Hagman's are involved paternally or maternally due to an adoption. Do any of these surnames ring a bell? Stephens, Thornberg, Anderson, Grueneisen, Greenland, or Keasts. Let me know if you can help. Thank you.
