Erik(Erich) Larsen and sons

I'm looking for more information on my 3rd great grandfather. As far as I am aware he was born on Dec 24, 1808. He married Johanne Margrethe Christiansdatter in 1857. He had at leas one son with her, Jens (James) Christian Larsen 1860-1934. There are possibly an additional 4 sons: Anton, Samuel, Anton, and Johan. I have records of Erik's parents, but they do not match his birth year. I have no information past birth for any of the other 4 possible sons.
