Family Relations Quiz

[Tirpitz]

Hello Everyone
I have a local village quiz which I would like to finish, the closing date is Jan 31st 2020.
I have 5 questions which have so far baffled me, and I am hoping you might be able to help. All have a family reference, either in the question or the answer, sometimes both.
The questions are all set out as a series of initial letters followed by a clue. Thanks in advance.
C.a.A.O. They, with family have made many TV appearances?
J.F. Actor whose wife, children and nephew are actors?
A.a.F.B. Brothers who played first professional cricket match together?
M.B. Very commonly involved in formal events?
T.C. This family takes its name from the smallest member?

Alec and Eric Bedser ?

Thanks JJ109, Moss Bros seems so obvious, but... wood for the trees and all that.
Thanks Cashier, I had James Fox, but could not find his wife, Mary Piper as an actress. I think it must be correct though.
Thanks Elliemay1, this has been suggested before, so I think it must be correct.
Thanks Kettledrum, Like you I am sure it is Alec and Eric and the 'F' in the question is a misprint.
T.C. still baffling me though

Very iffy Tirpitz - don't trust it

Toy chihuahua
All chihuahuas are in the toy "family" of dogs, and the chihuahua is the smallest, but although some are referred to as toy chihuahuas, toy is not an official name.
