My great-grandfather, Hubert Joseph Loughery, came to Boston, MA. (lived in Roxbury area) in about 1855. He married Mary Jane McDermott (from Roscommon, Ireland) in 1857. They had 3 or 4 children in Boston area and then the family moved on to San Francisco in about 1864 or so.
Hubert Joseph Loughery's obituary in 1891 in San Francisco, CA. lists his Irish background as: Clondallin townland, (listed as Glendellon but another poster corrected that), Parish of Killygaven, County Donegal, Ireland.
Any help would be greatly appreciated. T. Roberts
