I never thought we would have a Burt connection..that would be a surprise. I am sending this to my Dad as his parents were Charles and Dorothy...I see you mention both of these names in your message. I think Dorothy had remarried though so not sure if Charles is the Thew or not. Dad will confimr for me and Ill email you when I find out. He will be excited about this as he had an extensive Thew search done which wasnt really connected to our family directly. We lived in Mosman when we grew up in Sydney so it is highly possible we are on track.
