Dennis McLaughlin

I'm looking for information about Dennis McLaughlin who arrived in Canada prior to 1847.  It's possible he arrived in North America in the U.S. first.  There's a family story that he and two brothers lived in Worcester, Massachusetts, before Dennis moved to Canada.

Dennis married Mary Duggan, lived near Wakefield, Quebec and had a large family:  Mary, William, Anne, Thomas, Catherine, Bridget, Sarah, Elizabeth, Patrick, Theresa, Hugh, Hannah, Dennis Jr., Helen and Alice.  Hugh is my great grandfather.

Any information would be appreciated.

Thanks.
