Kate, So sorry I got muddled, yes the family are the Bryants - Anna was nee Ford. Grrh sorry for your wasted time and effort. I also found a Broad Lane at one of the Tre..s, maybe it was on a later Census that I found them next to the Vicarage.
Back when the family were originally researched in the 1970s - Bill Lemin wrote in his dedication "My chief informant and friend in the picturesque country village of Altarnun, Cornwall, Miss Dorothy Climo without whose memory of the "Bryants of Broadlane, Altarnun", this story would have never been written, for she was the only person there who remembered them." Unfortunately, neither of them are still with us to ask if it was it in the village or outside the village. A cousin toured the village and couldn't find it and I wondered if was only a small lane that disappeared. Then when you look how it is spelt by Bill you wonder if it was one word, but I think it is two in the Census.
