In 1889 Ann became the second wife of widower Isaac Stambaugh.  That seems to have been the correct spelling of his name, even though Ann's tombstone bears the surname Stanbough.

According to the information Isaac provided on the Board of Health document when he and Ann married, he was the son of John Stambaugh and Catherine "Ham" (further research indicates it was Hamm).  He was born in York County, Pennsylvania, about 1828 and the family moved west, spending time in both Ohio and Iowa before being counted in Schuyler County, Illinois, in 1850.

Isaac was married first to Elizabeth J. Klepper on March 16, 1852, in Schuyler County.  They established their home in Hancock County and had at least five children together between approximately 1853 and 1869.  Elizabeth died in 1888.

The following spring, Isaac, 60, took for his second wife the spinster Ann Denison, who was then a bit over 50.  Charles J. Scofield performed the ceremony at Carthage on the 28th of March, 1889. Witnesses were P. D. Williams and Ada Allen.  Ann's age was shown as 50 on the marriage license, but on the Board of Health document, her age at next birthday was entered as 52.  It appears that Isaac and Ann individually signed the latter form.  Isaac's signature does read Stambaugh, Ann's less legible handwriting shows a different spelling.  Marriage Documents

Ann went to live with Isaac and at least two of his unmarried adult children on the Stambaugh farm in Pilot Grove Township.  Their time together was brief; Isaac died in 1901, after which the Stambaugh children, Jacob and Luella, remained on the home farm.

We lose track of Anna until 1920, at which time she was residing with her sister and brother-in-law, Sarah and Daniel Ebert.

From The News of Fountain Green, the Majorville column by Mabelle Campbell, April 14, 1926:

On Frdiay [sic], April 9th at 11 o'clock the funeral of Mrs. Ann (Dennison) Stanbaugh was held at Majorville.  Burial in our cemetery.  Rev. H. M. Bloomer of Macomb conducted this funeral which was well attended by friends of this good woman.  Many were kept away on account of bad roads.  Mrs. Stanbaugh has made her home with her sister, Sarah (Dennison) Ebert and husband for many years, and being of such a kind, loving and helpful disposition she will be greatly missed in this home.
