some data from Terhi Arpalahti suggests that he could be a soldier Matts Mattsson K who used a soldier name Udd(berg). 1761-66 Rautalampi RK p 179 Tyrinvirda has a Soldier Matts Udd, b 1747

There is a soldier (no56) Matts Matsson Kumpulainen, soldier name
'Uddberg', born about 1702. The military lengths tell that he was
enrolled 4.8.1725 and died in the battle of Lappeenranta 23.8.1741.
He was married 26.12.1721 Viitasaari with Brita Larsdotter Kauppi-
nen. Their children:
- Matts Matsson *22.7.1723 Vsri Aroniemi, bapt. 28/7
- Maria Matsdotter *18.3.1728 Vsri Säkkärinmäki, bapt. 2/4
- Anders Matsson *21.1.1731 Vsri Säkkärinmäki, bapt. 19/2
- Johan Matsson *3.2.1734 Vsri, bapt. 18/2.
There may also be a Staffan Matsson, born 21.5.1722, bapt. 3/6, but
am not quite sure about him belonging to this family.

I am thinking that this Johan Matsson MAY be the Johan Kumpulainen,
who married Maria Henriksdr Niskanen *13.7.1734.
