I am looking to trace a Kate Cairns who was given as the next-of-kin of my great-grand uncle Richard Frederick (Fred) Zimber who died in 1915 at Ypres in WW1. He enlisted in Fiji but gave her as n.o.k. and address as Wexford, Ireland. I assume (but don't know) that she was his fiancé. As his surname was German in origin he served under her name of Cairns.
