I only have the following on a Charlotte Challenger:
Born 5 mar 1820 in Camerton, Somersetshire, daughter of Thomas
Challenger and Mary Cook
But you no doubt already have all of that.
I have a Rosina but it is not the same one -
born 1885 in Welton, Midsomer Norton, Somerset
Father: William Challenger, b 1860, died 1918, married 1881 to Mary Paul
sister: Ada 1883
brother thomas W 1888
sister Louisa 1890
The name is unusual, though.
