It may be that Thomas Bevan was born in 1923 and bore his mother's maiden name:
Sep 1923 Lloyd Thomas B Bevan
Registered at Cannock 6b, 847
Ther's a birth for Frederick Arthur at Cannock in 1906.
There's a Job Amos Llloyd registered in 1903 at Walsall (not far away).
Quite a gap between these and Thomas Bevan though.
His parents marriage is most likely:
Mar 1904 Cannock 6b, 624
Bevan Martha
Lloyd Job
but that post-dates the Job Amos birth above.
Enough to go on?
