You are very lucky to be researching the Pearsalls as there is a huge three volume book regarding them. Hopefully, your relatives are in it. If someone has not helped you by now, I can look your relatives up for you (I have the CD of the book) or look in my census info since I have written all Pearsalls I find in the census'. My g-g-g grandfather, Jesse Abrams (Abrahams) was married to Catherine Pearsall. Also there is a website devoted to the Pearsalls on LI. Let me know if you still need help.
