Lots of Sinnotts in County Wexford, actually it seems to be the only place. Mine are from Kilmore area, Barony of Bargy and there are others in that area as we keep getting potential leads that don't turn out. Someone looked in Griffith's valuation for name and found them in western part as well. You are ahead of my search as I only go back to around 1800. 2Gfather left Wexford, via ship from Waterford, in 1850. So at this time, I only have his parents Peter SINNOTT and Mary RACKE or Mary NEVIL and a possible on Peter's parents as John SINNOTT and Anne ?
