Hi - I'm desperately trying to find Thomas Abbott JEFFERY (Abbott being middle name). Born circa 1790. Sons - Edward 1816, Frederick 1819, Thomas 1817 and William Abbott born 1821. All born in Plymouth. I can find nothing on father Thomas Abbott JEFFERY. Curiously, there is another William Abbott JEFFERY born in 1821 in Linkinholm, Cornwall !! I believe Abbott to be a family name. Can anyone please help?
