This is a big break through for me! I never knew that this family was in Onondaga Co., until I happened to find this in Google Books. "Mrs. Sophia Butler" was the sister of Tirzah Catlin Lankton. James must have gone to Pompey earlier than 1806 because their daughter was born May 17, 1801. Which means........ I've been looking in the wrong place all this time!!!! Oh well, back to my reading.
