Hello Jacqueline,
I thought I had replied to your message some time ago - but my reply does not seem to have appeared. I am actually your father Bernard's cousin and have completed our family tree as far as I can.
If you need access to this please don't hesitate to contact me. My father was William Martin Cronshaw, the younger brother of your grandfather, Thomas. I had not sen your father or his brother, David, since I was about 4 years old - but was reunited with them a couple of years ago, which was amazing. I look forward to hearing from you.
Regards June
