It's been almost a decade since your post ... but I'll share what I have learned recently.
Henry was the 3rd son of Joseph and Mary (Gilroy) Boyers.
His full name was Henry Charles Boyers. He was born on November 1, 1853 in Sculcoates England (now part of Hull or Yorkshire on Hull). This date is taken from the N.H. Vital Record Archive of his death.
The father and children emigrated from England in 1865, arriving in the Port of New York, on April 6, via the ship Neptune. My current guess is that Mary Gilroy arrived earlier.
The family lived in Biddeford, ME for about the next 20 years.
Henry Charles married Margaret Hanley in Lowell, Mass in 1880. I believe there were two children that died at birth, and one living child, James Joseph.
Henry moved to Manchester, NH before the 1900 census.
Henry Charles married Annie Keough on November 24 1915.
Henry Charles died February 5, 1930, in Goffstown / Manchester. He was buried in St. Josephs cemetery in Manchester (location O-87). I have not been able to locate a marker.
