Thanks Arranroots. Yes, Jane is listed as a Paper Dyers wife also on the 1860 birth cert. of her son Louis George Chauveau. Jane died in 1877, as you say, at Bowling Green Cottage, Knighton, and is said to be 'wife' of Louis Nicolas Chauveau. I'm still awaiting birth cert. of son, Edward John Chauveau, 1865 in Clerkenwell district.
