Hi Owen
I have interloped into this post as the place names interest me but I am confused/intrigued as to what you are looking/fishing for. In date order, the collated info posted on this thread (working from most recent data date):
A Hugh Henry d. 1904 in Coleraine. Admon states "late of Ballyrogan, Liseall, Garvagh Co., Londonderry", farmer, widow (wife) Bridget. Catholic.
A Hugh Henry married a Bridget Higgins in 1891, civil registration Coleraine, Catholic Church marriage, Garvagh
A Hugh Henry b. 1871 or 1874.
Hugh Henry b. 1874. Baptised Presbyterian. Parents Samuel Henry and Rachel Taylor (who married in 1865, macosquin Presbyterian). Samuel and Rachel had 8 children, all baptised Presbyterian, macosquin). I think this Hugh Henry has been discarded as a possibility?
A Hugh Henry b. 1870. Parents Rose Ann and Hugh Henry. (Where? Garvagh? Assuming catholic baptism - refer collated info below)
A Hugh Henry married a Rosann Kelly 1867 Garvagh RC. Father of Hugh listed as James Henry. Father of Rosann listed as John Kelly. This Hugh and Rosanna Henry appear to have baptised a daughter (Mary Ann or Mary Jane) in 1873 Garvagh. Daughter Mary Ann/Mary Jane was baptised Catholic.
Do you have the dc for Hugh Henry who died in 1904? Is this the man you are trying to research?
Do you have mc for the Hugh Henry marriage to Bridget Higgins in 1891? Any father names listed?
Did Hugh and Bridget have any children? If so, when and where? Names of children might provide clues.
With clues from the above we might be able to sort through possible parents listed in this thread (and others) for your Hugh Henry....
