Griffiths Valuation for 1859 shows Samuel Black as having plot 4 in Terrywinny (spelling varies). That was just under 15 acres, and is still a farm today off the modern Terrywinny Lane. You could call at the farm and see who lives there today.
The Valuation Revision records show the farm passing to Jane around 1881 and then on to William in 1887. William appears to have died intestate on 20.1.1900, according to the PRONI probate records. A James Black of same townland died 2nd Aug 1929 and left a will (which should be in PRONI)
.William’s death aged 57:

Family looks to have been Presbyterian judging by the 1901 census. In 1911 there were 2 Black households there, one Presbyterian and the other of “other persuasion” as they described themselves.
Family seem likely to have attended Orritor Presbyterian church. Its baptism records start in 1831 and marriages in 1827. The only copies of the baptism records and of the pre 1845 marriages are held by the Minister. If you want to search them you would need to contact him/her. Post 1845 marriages are in PRONI and are also on-line on the irishgenealogy site. Presbyterians generally didn't keep burial records.
