Hi, how lovely, it seems we are related as Ernest Oldham was a brother of my grandmother Clara. She has three older siblings, William (Bill), Ernest & Rose (Rosa) these were all children from her Father's first marriage. I am in regular contact with Rose's daughter Norma who would be your 2nd cousin (I think)! It would be lovely to hear more from you but not sure how we get in touch? I believe Ernest emigrated to Australia from Macclesfield, Cheshire, UK?
Please keep in touch.
