Hi,
I have your aunt's parents Thomas Bidgood and Lucy Ann Bristow in my data and can take you back several generations on the Bidgood side. They are part of my One-Name Study of all Bidgood and variants. Let me know if you are interested.
I am sorry that I do not have any information on their children including your aunt to help you in your quest.
In fact it would be very helpful to me if we could exchange data on your Bidgood line since there are gaps in my records.
If you are willing please contact me directly at:
