Niels Arnesen og Inger Thomasdatter i Lillesand

[gj13197]

In my wife's ancestors tree I found a Niels Arnesen. I would like to know who he is.

I found he married Inger Thomasdatter(Humløya) 10/3/1812 in Vestre Molland as you can see here:

It's possible to read he is coming from Kepple in "Bukkens sogn"(and something else I can't understand).
I had a look on 1801 census for "heile landet" and found just "Buchen sogn" without Kepple gard, and no Niels Arnesen.

I found 3 children born in Humløya:
-Anne Elisabeth 22/6/1813 (Niels was a "matros")

-Thomas Christian 20/2/1816

-Arent 16/9/1818

Then I found he died 4/9/1848, in Lofthuus(is it the farm ?), at the age of 82 years old. But is he the same man ?

So he was born around 1766, but where ?. I can't understand his job in Lillesand.

Thanks for your help.
