Holly (Hetty) Blacketer, b. 1793 in NC; daughter of John Blacketer & (unknown) married John B Lockman, son of Ann Kirkland & husband, Vincent Lockman [b. 1763 of Orange, NC; d. 29 Oct 1843 in Medora, Jackson, IN]. Holly & John B Lockman were married 25 Jan 1816 in Mercer Co, KY.
Just checked this source: Bartholomew Co, IN Marriages: "Bartholomew Co, IN, Marriages, 1821-1920" - Carolyne Stultz compiled set of cross-indexed marriage books; parents included for marriages from 1882. email : Kattyjo15@cs.net
There is no listing of father or mother of bride or groom [1882-1920] in Bartholomew Co, IN, for your specific individuals, but there were several brides, grooms named Lockman or Blacketer, who married in Bartholomew Co, IN.
Some births for your surnames, not your specific individuals, are recorded. Part of this database is open by subscription.
It would be helpful to obtain BMD - birth, marriage, death certificates - for many of your ancestors.
To verify the state or county address - in order to request BMD certificates, see the below web site. Asking first at the county level - when the county is known - is my preference: http://vitalrec.com/in.html
Note town mentioned above - Medora, Jackson Co, IN.
Below are some possible, generic interpretations of information from the LDS pedigree file. Please forgive any mistaken dates, as I'm referring back & forth to Internet pages with nothing printed out for reference.
There may not have been any 'twins' - but since records were entered by several submitters, same date of birth for different siblings, or same child, with name altered - may account for appearances.
Apparently there were two generations with individual named "John Jefferson Lockmon/Lockman".
If "your" John Jefferson Lockman, born 23 May 1852, was born 'out-of-wedlock' to Mary Lockman - the vital record dates seem to indicate that Mary Lockman was age 17 and James Hugh Tayler was age 15 at date of birth in 1852. [sic, spelled Tayler but not to rule out 'Taylor']. You may have good reliable sources that prove the above status. A birth certificate, from Columbus*, IN, might confirm name of natural father.
After several years of genealogical research, one finds many similar stories. Again it is not unusual for the same unwed parents, to marry belatedly, after one or more additional children have been born. Less common is for the firstborn child to retain the mother's surname.
