Ancestry.com so far I don’t see it in 1718-1721
Sölvesborg birth records don’t go back that far.

but have not yet found records to actually link him to Helena & Petter.
https://www.myheritage.com/names/helena_lilljeborg claims Helena was born in 1726 and married in 1752.
But the Sölvesborg records for 1752 are badly damaged. Can’t find Helena in 1726 in Glimåkra.
