Anyone doing research on the Billingsley family needs to check out the book,"Billingsley Family in America" by Harry A. Davis, published in 1936.
This book is invaluable to any Billingsley researcher and is often called the "holy grail" for Billingsley research.
I was lucky to have my mother actually named in the book and from her & my grandmother, I could trace my ancestors all the way back to England and beyond.
This book has helped in my research very much. It gives great starting points for further research. From this book, I have found relatives I didn't know about and some that I did.
From further research I've done, I have been able to find pictures of some of my ancestors homes that are still standing; both in the USA and in England. I also learned about the Billingsley family reunion trip to England that is held each year.
This book contains a wealth of information about the Billingsley family and their life after coming to America.
