But,
I think OP is concerned of his personal security.
Where the beneficiary and his/her relatives may threaten him (physically) once the knowledge of him owning bitcoins is disclosed.
Oh you mean that OP wants to pass some coins to some beneficiaries, but is worried that he may be threatened by them?
Well, it's a personal situation so let's not go deeper. But, it makes me curious because if someone wanted to give me bitcoins, I wouldn't threaten them.
