I think that your ancestor was Christen Andersson, born Nov 6th 1859 in Västerstad parish in Skåne. His parents were Anders Mathiasson and Elna Christensdotter, Västerstad n:o 20.Therefore his americanized name could likely have been Christ Anders Mattson.
He left the farm Västerstad n:o 4 in 1888-03-22 for "Amerika". According to scanned images of this headstone (on ancestry.com), he was born in 1859 and died in 1939. (wife Mathilda lived 1865-1947)
Västerstad is situated in the center of the Scania county, here: http://maps.google.se/maps?q=V%C3%84STERSTAD,+H%C3%B6rby&...
