Hi Mark,
Your case study on the parentage of Eliza Mahala Smith is interesting. Thanks for sharing it and giving others a chance to learn from your experience!
There are three pieces of evidence working against the theory that Eliza was married to a Smith:
a) When Eliza was indentured (bound) to Mary "Polly" Bollinger, her surname was Smith. See minutes of Lincoln County Court of Pleas and Quarter Sessions for September 1837: "Indentures. Eliza Smith bound unto Polly Bollinger until she arrive to the age of 18 years." If Eliza was born in 1832, then in 1837, she would be only age five and obviously unmarried.
b) When Margaret Sebach executed her Lincoln County will on 25 July 1843, she referred to Eliza with the Smith surname. In 1843, Eliza Smith would be only age eleven and unmarried.
c) Eliza's surname is consistently Smith as a child and through 1850-1900 censuses and Eliza's children carry the surname Smith. As you point out, no Smith husband is ever in the picture.
Eliza Mahala Smith possibly was the orphan of a Smith couple, although when a child is bound out the court minute docket "most often" will say "orphan of ..." Possibly, the original indenture (if extant, is at the North Carolina State Archives) would have more information although the bond typically is the same as the minute docket entry.
Possibly Catawba County, NC, minutes and/or bastardy bonds show Eliza Smith as an unwed mother.
Thanks again for sharing,
