Hm, interesting. The Englands were well-off Catholics, but their next-door neighbours, the boys that is, went to Wesley for a bit, I think; or if they didn't, they had friends who did.
So Frederick (Jr) didn't marry, or didn't have a surving wife or children, or maybe was furiously estranged from them. Hmm. I hope not so.
From the people he was associating with in the early 20th century, he is likely to have been a member of the Irish Volunteers, or to have emigrated into arty circles, or to have joined the British Army, or to have worked on as an engineer or in the bank or some other middle-class place - unless he was destroyed by the slaughter of any of the wars that crossed Europe at the time.
