They are held in my mother's name ("The late Mrs...etc")
This is a follow up to my earlier response to your question. I've double-checked with the 2 savings institutions involved. They confirm that the accounts are held in my mother's name (NOT "The Late Mrs... as I told you earlier).
Thank you JGM - excellent service. One more thing - d'you know a suitable form of words (or a site I could find such) for
the legacy ?
