Abigail Mottice Creighton was the second daughter of Peter and Pheby Mottice to be married. According to an 1821 edition of the Ohio Repository, she married John Creighton on June 28 of that year.
Her husband, John Creighton, appears to be the same individual who married Abigail's sister Margaret in 1816. This could be explained by Margaret's untimely death, perhaps by childbirth. (See the post on Margaret Mottice Creighton here.)
Of note is that the Waynesburg Presbyterian Church records show that at the formation of the Church on August 31, 1821 -- one month after Abigail Mottice's marriage -- John Creighton 2nd and his wife Abigail were admitted as congregants.
Abigail's birth date is uncertain, although one researcher lists it as "about 1795", which is consistent with what I estimate Margaret's birth date to be. She is identified in Peter Mottice's will as one of his four heirs, along with her sister Sarah and brothers John and James.
Abigail died on May 22, 1858, according to a report in the Ohio Repository. The executors of her estate were listed as John Mottice and John B. Mottice.
