I can provide a short bit on Bill's wheels up in the Jaguar and the poor old SEngO being left behind as Bill departed courtesy of Messrs Baker and Martin. At SEngO's dining out he was presented with a Pilots Flying Logbook in which it says something like: 'Captain and 1st Pilot - 4 seconds'.
Regarding AFCs to others in the family, the best I can do are the Sowreys. As to other family awards: Rhodes-Moorhouse father and son VC/DFC, Peter Squire and his Dad both DFCs but Dad has a DSO as well. Major Mike Keilly (SAS Oman) and his Dad DSOs. There are various combinations of VCs and GCs with family connections in the Army but will need to look those up.
Sorry TTH not to be able drop a few more names in but think Whitworth-Jones father and son spring to mind for DFCs.
