See if this helps or is correct. I think William P. Lund was born about 1816 in New Hampshire, probably Hollis. He married Mary E. (Jones) Blood. It appears Mary was quite a bit older and born in MA. I believe John Lund was a son and here is some marriage information from the family Search web site:

I am not sure who Mary's first husband was but still looking. Do you think this is a match to your data?
