I read with interest of your search for descendants of Ambrose Taroni.
I am a great great great grandaughter of Ambrose Taroni and I will try and outline some of our bit of the family line for you. My mother Christine Davies of New Dock, Llanelli is the daughter of Christmas Evans who in turn was the son of Maud Williams. Maud was a daughter of Selina Taroni.
Maud gave birth to three children, Bernard Taroni Evans, Eva Taroni Lewis and Christmas Evans. Bernard and Christmas are both now sadly deceased but Eva resides in a care home in North Wales.
Annette Taroni Bentley, daughter of Bernard, now resides in Hockley Hill (strange that so many Taroni's seem to have gravitated towards Birmingham).
Eva's daughters, Rhiannon Jones and Eirian Pugh now reside in North Wales and Tregaron, Ceredigion respectively.
My mother, Christine Davies and my aunt, Elizabeth Jones live in Llanelli.
On the 1861 census there is another daughter for Ambrose and Mary, called Gazzella and a son named Francis on the 1851.
Selina and her husband were both teachers and held night classes in Llanelli. Rosilia / Rossillia was a dressmaker.
Annette has collected much of information about this side of family and I'm sure she'll be very interested to know that she has relatives in Birmingham! I'll get in touch with her to see if there is any more information of interest that we can pass on.
