I'ld just never heard of them, that's all.
Mum lived most of her life before her marriage in Narrogin and Dad lived in Yunndaga, Collie and then Narrogin, where they met. They spent their married life in Sydney. I still have a lot of remote cousins in WA, mostly in the Perth area these days but still others in the Narrogin area. Dad's parents were from Victoria from the Goldfields areas. They went west following the gold and then changed to coal when they moved to Collie.
I'm sure we don't have any genealogical connection apart from families living in the WA countryside. We'll eventually find out if there is a connection when we end up sharing a WikiTree profile.
