Hi Per,
I looked in Färgaryd for a birth on 4 March 1785 but couldn't find him. However, there is a birth on October 23, 1785 for a Jacob Persson, Father : Per Knutson and mother Kierstin Jönsdotter.
Färgaryd CI:2 (1752-1824) Image 1230 / page 241 (AID: v92273a.b1230.s241, NAD: SE/LLA/13099)
On this page at Söra Glasbo at the top is Per Knutson and wife, Kierstin Jönsdotter, with son Jacob. Am I right that the birth date just got mixed up when they moved to Mårenäs?
Långaryd AI:11 (1795-1812) Image 179 / page 177 (AID: v92958.b179.s177, NAD: SE/LLA/13259)
Thank you so much for helping.
Sue
