The name of Helen H. Toucey (spelled Hellen H. Tousey in the census) appears in the 1850 U.S. Census for Fairfield County, Connecticut, with the family of Jacob and Eunice Tousey/Toucey. The IGI portion of FamilySearch provides this birth record:
Helen Hildreth Toucey was born to Jacob Beers Toucey and Eunice Burr Clarke on December 11, 1849 in Newtown, Connecticut. Her death date is listed as January 29, 1885.
THE TOUSEY FAMILY IN AMERICA, available at The Internet Archive, states that Helen Hildreth Tousey married William Nice Taylor on September 15, 1875. They had a daughter, Eunice May Taylor, who was born in 1883. Eunice May Taylor married Garfield Rogers.
Mrs. Helen Toucey Taylor is buried at the North Monroeville Cemetery. Her tombstone is elevated, supported by four legs. It would be interesting to know more details about her life, and learn what brought her to Ohio from Connecticut.
