I am having another attempt at finding Rosetta Jones. This worries me for a few reasons. The Rosetta Jones born in Pontypridd died there later in 1893 according to a death registration on Ancestry.
I found Rosetta Jones born Merthyr Tydfil in the 1901 census. She is with her family in Merthyr and her father is William Jones, head, married age 40, Coal Miner, born Liverpool Lancs. Rosetta is aged 9 and born Merthyr.
The marriage certificate we have for Rosetta, which we know to be correct, shows her father to be John Jones, occupation: Verger.
The details on the marriage certificate suggest as Mull has mentioned, that Rosetta was the sister of his Taid. There isn't a birth registration for her in the right area, it is a fact that the other children they had were registered in that area. Then she isn't with the family in the 1901 census, just Eliazer b1891. She would only have been 8 in 1901, so you would expect her to be with her parents.
I have found a possible Rosetta Jones in the 1911 census. She is in Bryn Hyfred, Llanfaes, Beaumaris and the servant in the household of Ellen Pritchard. This shows she is aged 18, single, a Kitchenmaid, born Llandegfan, Welsh nationality, speaking both languages. The head of the household is Ellen Pritchard, age 66, single, living on private means born Anglesey. She has 5 servants including Rosetta.
This looks very likely to be her. I cannot find her in the 1901 census, nor anyone like her.
It makes me wonder if she was an adopted child of the Jones family. I wonder if the parish registers of Llandegfan might shed some light on this.
To be continued.....
