Just wanted to give an update on my message posted earlier this year. Thanks to the replies I received I was able to follow up some more on Sarah Jane Haughton. I got a death cert for her showing she died in 1951 aged 76 and still single, her occupation was a farmer. The address was Balliniavalley Woodenbridge, very close to her location in the 1911 census.
Her death was registered by her daughter Martha Keogh. Further research shows this daughter was not connected with Sarah Jane's Abduction in 1891, but was born in 1905, when Sarah Jane would have been 31, and registered in Dublin. This Martha is actually recorded on the 1911 census in the household with Sarah Jane, and her sister, mother and uncle, she is recorded as Martha Thomas Ena!
I also found that the Wicklow Newsletter covered the abduction case in great detail, and even reprinted Sarah Jane's love letters to John Doyle.
I am still interested in hearing from anyone connected to Sarah Jane, or her daughter Martha Keogh nee Haughton.
Thanks again for you help.
Margaret
