Hi,
Sorry for the delay in replying. My branch of the Seaver family is quite separate from yours - mine are the Seavers from County Dublin. These were the Irishs Seavers who always lived in the farming communities of north County Dublin. Yours were from England and they immigrated and settled in the north of Ireland, where Jonathan Seaver built Heath Hall, I think in the 1600's.. I can refer you to a couple of people I know who are from your side of the family, and also, a second Seaver family reunion is planned for later this year. The first one was in Dublin 3 years ago. Good luck with your research!
