But who is Andrew? In the database I have a brother for Hans named Jacob Andreas Funk Lund, and I have that he died 24 Sept 1871. But I have that he was born 23 Jan 1846. Could Andrew be an uncle? Is the birth year wrong on the grave marker? That seems odd as I would think the family would want a correct grave marker. I'll have to look for a grave marker for Jacob and see if he is buried somewhere else. I would really like to find out how these brothers died as they were both so young (25 and 28 years old).
