Look for my tree under "Sara Gaarde Family Tree" on Ancestry and then search in my tree for John Clark. He is the brother of Jesse Clark. Please let me know if you can get into my tree or not.
I am sorry to say that I don't think I have the name of Jesse Clark's wife. She died before 1850, because in the 1850 Lorraine census Jesse Clark age 80 is living in the home of his son-in-law and daughter, William and Susan "Beebee."
(Daughter Triphena Beebee married a man surnamed Gordon.)
Also, I find in 1870 census of Kaneville in Kane County, Illinois, Warren Beebe and wife Amelia and living in their house is Susan Beebe age 67. So they were still in Illinois for 1870 census and also William Beebe is not listed in 1870 census with them.
I have not been able to find William Beebe, Susan Beebe, or Warren Beebe anywhere in 1860 census. Have you found them in 1860? I think they moved from New York to Illinois sometime in the 1850's.
I looked up Jesse in the Morrison book, and unfortunately his wife's name is not listed there. However, listed with Jesse is the name of one of his sons -- Nathaniel Perkins Clark who was born 3 August 1797 that would be back in Montgomery County, NY. Now that "Perkins" rings a bell with me although I can't find anything on paper. Jesse's wife's maiden name might have been Perkins and don't quote me but for some reason by brain says "Tabitha Perkins" or something like that. I'll look in one other place.
