Ella May Blair N E Graham

I have information on everyone on my family trees but I've hit a wall with a great great grandmother. There is little to no information anywhere on her. Here's what I know so far; Born Ella May Graham, married Frederick Blair at Tingha, NSW in 1927. She has a brother named James Henry White, apparently there were 6 other siblings but I have no info on them, It's been said that she may have came from Terry Hie Hie, NSW originally but I don't know that for sure. Any information will be greatly appreciated. Thanks
