So, my 2xgrandfather, Patrick, came over from Ireland in 1887. He came to live in Massachusetts and married a Swedish woman by the name of Augusta Hummelgåd*. who gave birth to my great grandfather, James. I really just want to know who his parents were and where he came out from. I seem to be hitting a brick wall anytime I try to find his point of origin or who the rest of his family was. The same is true for Augusta.
*there are several variations I've seen including
Hummelgood, Hummelgard, and Hummelgord.

If anyone has any information or advice it would be really appreciated.
