I would like some help translating the birth record for Peter Gustav G4F1-W99

He went by Svensson as his surname later on.

Carole McIntyre

1830 Peter Gustaf illegitimate - born 14, christened 17 - Maiden Maria Lundgren's son who was called Peter Gustaf carried (fört) by widow Catharina Söderman

I am assuming that fört refers to being held at the christening.
