I am looking for anyone who may have information on three brothers: Peter, James and John Simpson who came to early America from Ireland. My grandfather told this story, but no one seems to know anything about it. He also said we were related to Ulysses S. Grant. My grandfather is a descendant of Peter Rine Simpson and Elender Faulkenbury. Peter's father was Thomas Simpson. I know all about the research going back to Richard Simpson, Sr. in Baltimore, Md., but it doesn't fit the three brothers from Ireland story. Can anyone help me, please?
