Spotted this slightly Germanic surname on my blog and like anything you go look at in detail the facts crumble in your fingers and you wish you had left alone.
I had Ronald Edgar Coggan SHUTTER married Helena Emily Sarah LAWES married 14 Apr 1931
I found his birth at Chard and baptism 6 May 1896 Crewkerne Somerset with the surname SHUTLER
I also found on Find My Past his death at Weymouth and subsequent burial 2 Mar 1973 West Lulworth
and that's where the mystery begins I found Helena's death 1964 Weymouth but when I looked at a transcript of West Lulworth burials http://www.eastlulworth.org.uk/burials_1921_1991.html no burials are recorded for this or any similar surname and no burials in 1973
