Are you still researching Theophilus Grant??? He was my gggrandfather and would love to see what you have since your last post. I started working on Sarah Duncan's family but hit a brick wall too.
Email me at smlikiht@yahoo.com and I will let you know what I have
Theo parents were Eliza and Suzanne Gaylord. I cant remember right now which census it was either 1850 or 1860 they were living next to them in Missouri.
Looking forward to hear from you
Wanda
