some Mats Tarfvain had had children in Viitasaari..1714..twins Axel and Erik..died 1714

there was also a Samuel, Pahl Pahlsson, Pahl Thomasson and Henrik having children who died 1716-1730 in Viitasaari, all in Suovanlax whenever a place was specified

1711-1760 6 Tarfvain children were christened in Viitasaari
Mats was married to Maria
Pahl to Walborg Pahlsdr
Samuel to Elin Kärkäis
Henrik to Lisa Panain (3 children)

collectively they had only 6 children in Viitasaari 1711-35 (Suovanlax whenever a place was noted), so either the records are bad, they had few children, children were registered elsewhere
