New Clue

This week a found a small clue as to the Roberts family that may have adopted William H., Glorian & Susan (Hawley) Roberts.  In the 1850 & 1860 census records Joseph Pelletier is listed under the name Pelkey.  I Noticed in the 1860 census that the last person listed in their household was a 78 year old widow named Hannah Roberts.  I know this isn't proof but it makes sense that this lady named Roberts is likely the person who adopted the Hawley orphans.  Now I have to find Hannah's husband.
