I am looking for Garret Voris who was born about 1770 probably in Westmoreland County, PA or York County, PA. He is listed in the 1798 tax list and in the 1800 census with Ralph/Roelof Voris and Ralph/Roelof Voris Sr.To me this suggests that they are his brother and father. He married Mary or Polly and they had four children in Westmoreland County, Pa--William, Ralph, Ann and Hannah (my ancestor).
The family moved to the Cincinnati, OH area in 1803.Garret died sometime around 1820 and Mary moved with Hannah and her husband to Madison, Indiana.
Does your book have a Garret that matches these facts?
