There are a large number of records relating to Sergisons in Ireland; many of which are now categorised as being in Northern Ireland. The following families were initially located in Northern Ireland.

Joseph Sergison (1800-1848), a weaver probably from Tullynish, county Down. Some descendants recorded themselves as Presbyterians and others as Church of Ireland. Only two generations in Northern Ireland have been found. This is the descendant report:

Joseph Sergison (1835-1901) was the son of Samuel and a shoemaker in Belfast. The family largely adhered to the Church of Ireland faith. This is the descendant report:

John Sergison (1800-1870, a shoemaker from county Down who may have fathered seven sons and a daughter. Son Joseph was a soldier in 13^th Regiment of Foot and son Richard became a schoolmaster.

The final family in this section is that of John Sergison (1781-1865). He was a Dublin based jeweller who followed the Roman Catholic faith. His son John remained in Dublin while his son Arthur (1811-1888) moved initially to Liverpool and then onto Middlesex. He spent some time in USA before returning to England where he died in 1888. Two of his sons, Angelo and George, seemed to have remained in the USA. This is the descendant report:
