Who is this woman surnamed Crail born c1815 in Ohio? The first name is nearly illegible. It does begin with the letter 'M', but appears to be Mrs. Could this be Mary A. Crail? Warren Twp. is just east of Indianapolis/Center Twp.

James Snyder married Nancy A. Smith on 23 Apr 1843. Lucy Simmons had married Collins C. Smith on 10 Oct 1840 in Switzerland Co., IN. [Nancy & Lucy are the same person.] C.H. Smith was a product of that marriage. There are no apparent ties between the Smith, Snyder & Simmons families.

Could this woman be Mary A. [Jones] Crail? Perhaps. The age is close, off by only 2-3 years. The birthplace of Ohio is spot on. I suspect that the family was in central Indiana. Sylvester, John & Aaron were living in southern Hamilton Co. or in rural Marion Co. George was in Indianapolis, or close enough to enlist from there during the Civil War. In 1860, he was old enough [17] to have been a farm or day laborer & living with another family. James B. Crail may have died between 1854-59.
