Looking For Information about Nancy Agnes Miller and Catherine Snyder?

I received the following email from someone looking for information about the parents of Nancy Agnes Miller (abt 1800 - 1856), and about the ancestry of Catherine Snyder (see below).

If anyone has any more information, please respond below in Comments or write me at miller.and.bradford@gmail.com. Thanks!

1.    I found your discussion about William Miller of Fayette County, PA  at genforum.

I am spreading a wide net hoping to break through abrick wall.

Looking for the parents of Nancy Agnes Miller (abt 1800 - 1856)

and her husband  David Shafer (abt 1800-1879)

Shafer could be spelled Shaffer, Schaffer or Shaeffer

 

David Shaffer purchased land on Feb 6 1837 at Stark Co, Ohio. 

1850 Federal Census Osnaburg Twp, Stark Co, Ohio. 

    David Shaeffer, M, age 51, born in Pennsylvania

    Nancy, F, age 50, born in Pennsylvania

    Henry, M, age 15, born in Ohio, Farmer

    Daniel, M, age 11, born in Ohio

    Nancy, F, age 5, born in Ohio

I do not know where David abd Nancy were born in PA,  The children were all born at Stark Co, Ohio

Does anything look familiar?

2.   I am also related to a Catherine Snyder(1797-1856), buried Hols Co, OH.  Her parents were George Snyder/Schnieder and Margaret Miller of Holmes Co.  Margartet was of Swiss-German descent, daughter of Martin Miller and Anna Maria Eck of Derry Twp, Westmoreland Co, PA
