If you are still interested I would be happy to try to help. My Mother is a Beggins. I have been able to verify a lot of information. The key is the spelling as the exact spelling of "Beggins" is unique.
I am in the process of cleaning up my family tree and redundancies and inaccuracies. My Grandfather was James Peter Beggins, son of James J. Beggins and wife Belinda "Linda" MacNeila/ Linda MacNeila was from Swineford in Mayo County Ireland. I have access to the 1901 Ireland Census as well as other documents. If you want help, I am happy to share what I find.
