Find Ancestors

Hello, I have hit a brick wall and aould appreciate any assistance. I am looking for any information regarding the family of Eileen Loosemore b 1928 in Pontypridd Wales. She married Tom Speight and they had 2 children John and Anne and they all emigrated to Australia. My brickwall is about Eileen's father's other families. Edward Loosemore was married 3 times, first to Elizabeth Bridgeman and they had 4 children, second to Annie M Jones (eileens mother) then to Lilian Dale. All of this happened in or around Pontypridd Wales. A couple of specific questions, 1 what happened to the children of the first marriage when Edward married Annie, 2 was eileen in an orphanage or were they all in the work house (eileen did not live with her parents till she was 8) what were the local places that she/they may have been in, 3 Lillian Dale was supposed to have bought 2 daughters into the marriage, who were they, what happened to them? Apparently Eileen arrived home from school one day (she was ?15) to find that the family had moved without telling her. Any information regarding these families would be most appreciated. (Eileen has alzheimers and is unable to talk about the family) Regards June
