Sjoberg, Erik

[Charlie Soule]

Born Erik Jonsson, apparently in Nedre Ullerud on July 6, 1811; died March 5, 1890 in Skillingsfors.  I find him in Mölnbacka in 1832/1833 (509.18.20400), marriage to Anna Eriksdotter November 17, 1833 (509.32.26400) moving to Nor parish in 1834 (#40 509.23.27200), living in Edavalla Manufaktur in 1834-1837 (510.32.99100, 510.34.23200), moving from Nor parish (Edavalla) October 15, 1837 (510.18.21200) to Köla parish (Adolfsfors) October 28, 1837 (502.55.42300) and moving to Skillingmark (Skillingsfors) on Oct 13, 1839 (502.55.38800), where he lived the rest of his life.
 
Two questions:
 
 1) Can someone help me find his birth record?  The date 6/7/1811 is used consistenly, but I can not find a birth or census record around near that date or year in Nedre Ullerud that matches well.  
 
[I'm not sure it is the same man, but perhaps the earliest record I find for him is found moving from Nedre Ullerud (#49 509.23.26500) to Nyed (#104 516.39.6700) in 1830, and back to Nedre Ullerud in 1832 (#102 516.39.7400).  If so, and if 509.23.26500 says he moved from Bergstorp, then perhaps he is Erik Jonsson born 1801 to Jon Arvidsson and Margereta Olofsdotter (509.18.6400) - or more likely the one in the 1825-36 HFL born in 1812 (509.18.6700) who doesn't appear to be living with immediate family?  If so, I do not see him in Bergstorp in the earlier census - perhaps he is in Berg (509.16.86100) and (509.15.56200) - born October 1 (or September 30) 1812 - the son of Erik Eriksson?]
 
2) In 1836/1837, he appears to adopt the last name Sjoberg (510.34.23200).  Is it likely that this was to honor spiksmeden Anders Sjoberg of Mölnbacka (509.18.20400)  and an indication that he learned the trade from Anders Sjoberg?
