Find Ancestors

Hi i'm trying to find a few people. One being Fancis Storey b. 1900c. She married Jack Goulding b. 1900 c. I would have thought they were both born in the London area (east). The children they had are a bit of a mix up at the moment. Irene Ivy Lewis nee Goulding is my Nan born Golders Green 1920c. She has sisters, Eidie and Kitty and a brother Johnny. I've no idea of birth dates etc for these siblings. Ok, now for the confusing bit......My Nan also has two other sisters Elizabeth (Betty) and Lena. I know that these two sisters would be the youngest. However, Lena and Betty both had a different dad from my nan. Also, to confuse things even more, my mum thinks Lena and Betty are linked to the name Haynes or Hynes. Maybe Francis married again? I really am stuck. I'm also looking for Jack Goulding who married Francis. It's really difficult trying to trace people who have no birth dates, places etc. I've looked on the census but millions of Jack Goulding appear. I'm also looking for any info on my Nan's ex husband and Mum's Dad, Manfred Lewis. He was born in Pontypridd, Wales and died in 1977 at Hayes, Middlesex. He divorced my nan and maybe married a lady called Eve. They had two (that i know of_ children together, Tracy and Carol. Any more information on his family would be great. If anyone could help me i would appreciate it so much. This truely is all the info i have. Please help, i've hit a brick wall. Thanks, Claire x
