Find Ancestors

hi my name is ceri, is there anyone out there who could like me with finding my father,s parents and other relatives, unfortunaly he was put into a home by his parents when he was a baby . his parents names were annie mabel duk e and edwin john evans, whose parents were john duke and justina duke they came up from somerset seeking work, and abraham evans and i think his wife was eva gwendaline evans. edwin and mabel married on the28th february 1920 both 25,, on the 1929 electoral register they were living at 8 penner street newbridge south wales but they were not there in 1930 or any of the other streets near by. we believe in 1930 mabels youger brother baden was living in blaenblodow street newbridge and that his wife,s name was margaret. if there is anyone who can give me any information ,i would be very grateful as my father died aged 49 undergoing a heart bypass operation and this link to his family has died without me knowing them. thanks ceri
