Hi Karen,
I have looked in Brampton, and the Parish records I have around Aylsham, with no luck. But there is a Robert Esto/Easto/Eastic born Aysham 1854 with Parents Nathaniel and Elizabeth. I would expect Robert to be a few years older than Ann, as he was a widower when he married her. Not a lot of help I know!
If you want more on Ann Hudson's family will have a look in Brampton for you, John and Mary Hudson had other children, but you may already have this information.
Kind regards Eileen
