Risto Ristonpoika Hynynen currently has two sets of parents on Geni and i do not have enough evidence to determine which is the correct pair.
There are two boys born in Rutacko both baptised "Christianus", three years apart.

My source, which is Esa Hynynen's self published "Huna Suvun Vaiheita" (1984), clearly states that the father is Peder Hynynen but lists no primary source.
I have been unable to find any record for marriage or death. I have checked the baptisms of his two children and in both cases there is no patronym listed.
It is possible that date of death is 3 April 1790 but no source and I have not been able to verify.
