1737-44 RK p 183 Nykälä, m
plus later by e-mail, I have knowledge of 2 Pahl Nykanen from Pieksamaki from the 1700s. Name
Pahl refers to names Paavo or Pauli and one of them was Paavo Tanelinpoika
Nykanen (born 1708, wife Maria Hakkinen) and the other one was one of his
sons Paavo Paavonpoika Nykanen (born 7.3.1736). Unfortunately I dont have
any further knowledge of the latter (whether he was a soldier of whether
his wifes name was Suhoin) but he could be the one you were interested in.

Here is some further knowlwdge of Nykanen from Pieksämäki in RTF-format.
