Stephen Gilbert (son of Stephen) m.1857 Lurgan district to Sarah Ann Bell (daughter of Edward).
https://familysearch.org/pal:/MM9.1.1/FGCN-NZ3Stephen (d.1902) Gilbert's Will mentions lots of relatives which should make drawing out a family tree much easier- wife Sarah Ann; sister Margaret Ann Rountree in N.Z.; nieces: Annie Price, Mary Gilbert, Geanie Gilbert, Ealenor Gilbert; nephew Edward Gilbert's sons, N.Z.; nephews: William Gilbert, Stephen Gilbert, Henry Gilbert; executors William Gilbert, merchant, Belfast & Jonathan Gilbert, farmer, Aghagallon.
As the family seem to be Methodist (Stephen's Will mentioned a bequest to Moira Circuit) keep an eye out for other Gilberts who were Methodist.
