Suzanne forwarded your info on Bertha G. Olson to me. Bertha's husband Jan Magnus Eriksson Ekstrom was my great-great uncle. Are you a relative? If you would like info on Jan Magnus. I have the family back to a marriage in 1735. I did not have Berthe Marie 1829,so added that to the tree. The only diference in records is the birth record for Berthe Gurine is from Froland parish, Aust-Agder, not Arendal. I have Maren Johannesdatter's family, and Maren's father's family. If you do not have that, I will be glad to email them to you.
