Hm. My records diverge slightly from what you've written here. I show that Abraham Deputy (b.1789), husband of Elizabeth Webb and father of your Abraham Morris Deputy, to be the grandson, not the son, of Jesse Deputy (b.1719) and Sarah Collins (b.before 1745); and his parents to be Jesse and Sarah's son and daughter-in-law, Joshua Deputy (b.1765) and Mary Walton (b.1775).
I don't have a Jesse and Mary Deputy that would have produced an Elizabeth Deputy around 1790.I would love to find out more about that line, if you know descendants or ancestors that I might be able to tie to them from my Deputy family tree.
Also, there seems to be no record of any Deputies in the Union Cemetery in Milford on www.findagrave.com.Would you be kind enough to add what you have to that website?Or if you forward the information to me, I will be happy to add them.
