Private User , Thanks for the "look at." I am going to contact the profile owners as I don't manage this profile, but for males, I have never put in a "birth surname" - only for females who married and I had their "married name" along with the birth surname. If I do not know one or the other, I leave that one blank. I imagine a number of others do this.
This article (published in "The Finnish American Reporter" August 2000) helped me understand some of the Finnish naming issues, but it may not explain all: http://www.genealogia.fi/emi/art/article216e.htm .
If you look at Heikki's father Jacob Johansson Huhtala and his mother Maria Caisa Henricsdotter Kangas , it is just pretty hard to determine what name goes with who and where in my opinion. I think adding "Huhtala" to Heikki's surname at birth is likely to prompt a different kind of inconsistency since it is not a name on either his father's or mother's profile. Just my confused thoughts.
