Hello Suzy,
Have just found your correspondence on Beadon Davey's burial at St. Saviours Church, Rolleston, N.Z. I'm pleased to inform he does have a plaque headstone which several NZ descendants contributed to and erected January, 2013.
Late last year I tracked down the 30 acre block of land he farmed in Rolleston.
Beadon's second son, Henry, was my great grandfather.
We will be visiting the UK and passing through Somerset towards the end of July ( in just over a weeks time!) visiting Lilstock, Nether Stowey and Culmstock. I wonder if you or another Davey family researcher is living in this vicinity? Hope this message is timely, we leave NZ Monday am. JoCCEFM
