Hi there
Im now confident that Im a direct descendant of Anthony Morrison and Agnes Pedlar married 1814 in Hillsborough. Anthony died 1874 reputedly 84 years old suggesting he was born in 1790. They were from Edenticullo or Edencullo and appear in the 1864 Griffiths Valuation assuming there werent multiple Anthony Morrisons.
Their son John married Mary Ann Briggs at Magheralin Church in 1859 and had eight children, two of whom, James Andrew and Mary married two Mercer siblings, Eliza and John. Morrison and Mercer are very common surnames in the area harking back to the 1750s at least.
While John and Mary Ann Briggs has their children in Belfast James and Eliza lived in Culcavey.
