Hello there,
Well I have well and truly "Googled" for Lady Mountbattens(she is also Countess Brabourne,by her husband) eulogy at the Memorial Service of her son,but with no luck.His name was Nicholas Knatchbull by the way,and along with several other members of the Mountbatten/Knatchbull family was killed in a boat explosion by the IRA,in 1979.His identical twin brother(Timothy) survived.
What I have found(we don't live that far from them) is the phone number/address of Norton Knatchbull(now Lord Brabourne,as his father died last year)who is Nicholas' Eldest Brother.
As follows:~ Address
Rt Hon Lord Brabourne
NewhouseThe StreetMersham
ASHFORD

Phone Number

Sorry if this is confusing,but Countess Mountbatten of Burma is this in her own right (through her Father) was Countess Brabourne(through her husband) and is now Dowager Countss Brabourne.The Brabourne family name is Knatchbull.
Don't be scared of ringing them,they are a nice family!
