The name of the book we are talking about is the book
"Maryland Catholics on the Frontier" by Timothy J. O'Rourke. I got mine for $150.00 a couple of years ago from his brother who was selling them. I don't know if there are any left, but when I get a chance I will try and look up ypur relative Obadiah Layton from N.J.
