You were asking re possible Palatine connections - this I posted on Ancestry messages recently but will copy here:
There were Palatine Mueller/ Miller families who came in 1710. According to Henry Jones book, Palatine Families of Ireland, a John (Johann) Jost Miller is recorded in 1715 as head of one family likely settled in Wexford. His wife was possibly Ann Miller and she is listed as head of family in 1720 on Old Ross estate run by Abel Ram family, which estate was near what is New Ross now. There are possible children/ descendants - John Miller, Henry Miller, Thomas Miller and James Miller. These were made freemen at various dates ranging from 1748-1759.
There's a pretty good survey of the Old Ross estate, in National Library Ireland, dated 1818 but there's no mention of Millers there then. This survey is very detailed with description of farms, land, tenants & leases. So the Millers above had either died out by abt 1800 or moved out. If they moved, they could easily have relocated to the Tighe estate around Inistioge, I guess.
I can also tell you that in same NLI papers, there's an 1836 rental list for Abel Ram estate near Gorey, north Wexford – on this a John Miller is leasing land at Clonattin nr Gorey, Wexford. In 1813, there’s similar list for same estate containing a Lewis Miller, Esq – i.e. a gentleman, also leasing at Clonattin.
