Jessie Petitt Family Bible1 has entry "Martha and Mary Riddle was Bornd August 14th 1839." This would agree with the 1840 census, which lists 2 daughters of John William Riddle under 4, and with the 1880 census, which gives Mary's age as 41. But it would disagree with the 1870 census, which gives her age as 29, and with the 1900 census, which gives April 1841 as Mary's date of birth. (See Census Notes for Preston Pettit and John William Riddle.)

Her death certificate, file #11632, records Mary Fraley died 19 Apr 1916 in Rowan Co., precinct #7, age 76 years 8 months 12 days, married, born 7 Aug 1840 in Morgan Co., Ky, father John A. Riddle, mother unknown, attending physician J. Wilson, cause of death cerebral hemorrhage, burial in Black Cemetery, informant and undertaker Wm. Petitt of Crix, Ky.

Many of the details given by William Petitt are wrong: Mary was really born in Bath Co., and her father’s middle initial was not A. but W. Possibly Willie got Mary’s father confused with Pressie’s half-brother named John A. Pettit - if he didn’t know his grandmother’s name at all, he wasn’t likely to be too sure of his grandfather’s middle name. Mary’s birthday may have been 7 August as Willie gives it; the date of 14 August is from the Jessie Petitt bible, and there is no strong reason to prefer Jessie and Emma’s knowledge to Willie’s. But the bible entry was made shortly after Jessie and Emma were married, while both Martha and Mary were still alive, so I give it some edge. The 1840 census is my reason for preferring the 1839 year to 1840.

Rowan Co. marriage book 6, page 557, lists marriage of Harvey Friley, age 64, son of James & Nancy Friley, to Mary Pettit, age 68, dau of John & Adaline Riddle, on 11 March 1909, at the home of A. J. Brown, by Rev. S. J. Porter, witnesses Charles Kegley and A. J. Brown. It is a second marriage for both spouses. (The ages at marriage would suggest birthdates in 1844 for Harvey and 1840 for Mary.)

I cannot find Harvey or Mary in the 1910 census.
