Dear Jellyby
thank you so much for this reply. I was considering buying the QWR war book, but even at about £9 on Amazon, it seemed a bit much for 6 weeks. I imagine you have it...(Why does Rootschat think I am my husband, Ken?)
The family story says Frank was in the trenches, as a sniper, for only about 6 weeks before he went down with rheumatic fever and was then in hospital for so long that his mother wrote to the King to see if they had forgotten him (no record in Royal Archives and she was said to be practically illiterate!)
Effectively, his war was over. He still would not talk about it afterwards, though, like all the others.
I have no idea where to look to see if there is a hospital record. My mother thinks that it was Roehampton, but that was a place for people who needed replacement limbs, I believe.
I don't know if he was in this entertainment on Jan 23 as a convalescent or if he was pulled out of the line to be an entertainer; he was an excellent pianist, and a very funny raconteur.
When he reappeared in April 1917, and got married, he was a lance corporal in the RDC based at Frinton on Sea. He brought a lot of potatoes back with him to Camberwell when he got w/e leaves. Maybe potato peeling was all he could do after his rheumatic fever. I can't find anything about the RDC at Frinton, or St Osyths, possibly his base then, either.
Please keep looking. since I don't know where to go next!
yours
Jacqueline
