I don't have too much info on Cynthia Ann Sickles Watton, but here's what I have:
Cynthia Ann Sickles born Sep 13, 1822 in OH.She died Jul 12, 1903 in Shelby Co, IL and is buried in Watton Cemetery, Shelby Co, IL.She married Fealdon Watton on Apr 9, 1840 in Hancock Co, OH.Fealdon was born Apr 26, 1818 (place unknown) and died Jan 28, 1887 in Shelby Co, IL.He is also buried in Watton Cemetery.My sources are Inscriptions of Shelby County, Illinois Cemeteries and Hancock Co, OH Marriage Records 1828-1864.
Cynthia's father was John George Sickles (Sickels)who was born Jul 25, 1791 in Rockingham Co, VA.He died Jul 4, 1865 in Shelby Co, IL and is buried in Mud Run Cemetery, Shelby Co, IL.He married Rebecca Kelly on Dec 22, 1819 in Pickaway Co, OH.I have no other info on Rebecca.My sources are tombstone and Pickaway Co, OH Marriage Record 1810-1862.
I have a copy of John George Sickels Probate.It lists Rebecca Sickels, widow, and Synthia A Watton his child as heirs.Fealdon Watton was appointed Administrator.
Cynthia and Fealdon may have had a daughter.Rachel A Watton was born Dec 5, 1865 and died Apr 13, 1881 all in Shelby Co, IL.She is buried the same place as Cynthia and Fealdon.
Hope this info is some help to you.I am unfamiliar with the other names you mentioned.
