In 1860, Chloe is age 7 born in OH living with the family of Isaac Perkins in Centre township, Williams Co., OH (Williams Centre P.O.) on the following film location: 1860>Ohio>WILLIAMS>CENTER TWPSeries: M653Roll: 1052Page: 77
Perkins is a 59yo farmer born in Ohio.His family is wife Mary (age 53), daughter Rachel (age 28) and son Milton (age 18) all born in Ohio.
I did not find any enumeration for a G. W., Geo. or George in Williams Co. or elsewhere in the United States who could have been your Mr. Snelling, nor for Lavina or Lavinia Snelling either.
In 1870: an Anna Snelling is age 18 working as a domestic servant for a family named Obrist or Obrish in Bryan, Pulaski twp. an Ellen Snelling is age 18 working as a domestic servant for a family named McAna (?) in Bryan, Pulaski twp. another Ellen and apparent brother Alonzo, ages 11 and 9, are living with the Jedidiah Dawson family also in Bryan, Pulaski twp. All these children say they were born in Ohio.
I don't find a Chloe Snelling or Sneling anywhere in the US in 1870.I don't find any 11-20yo individuals named Chloe born in Ohio living anywhere in the US who could be an enumeration error for Chloe Snelling (i.e., a garbled last name),I don't find any 11-20yo individuals named Snelling who could be an enumeration error for Chloe.
Was she married by 1870?If not, either she was missed or she was living with other Snellings or she was enumerated under the surname of the other family.
