There was an Elizabeth Jones, age 14, born in Darowen on the 1891 census, daughter of John and Elizabeth, but he was a district surveyor.
I see that Mary Humphreys, wife of Edward in 1901, was also born in Darowen.
In 1891, there was a Mary Jones, b 1868, visiting the Red Lion in Darowen. She was also the daughter of John, the surveyor, on the 1881 census.
