Can my father's relatives keep me from seeing him?

My father is in the early stages of Dementia, and his relatives are preventing me from seeing him. I am his only child, a daughter. I live 2 houses away. They have even hired a caretaker, Mon 9:00am to Friday at 2:00 pm at his place, and she told me that I am not allowed to come to visit my father..... Well, I visit him every afternoon/evening still, but stagger the time so an not to be too predictable..... Well, for the last two weeks, or so, I noticed that family coming and going..... Sundays, I am there with him to prepare his breakfast, etc... and he welcomes same, we have much conversations together.

I have contacted a lawyer to start issues a letter, etc and then to start the relevant proceedings...

No one will keep me from seeing my father...... Pronto, I might take my time in doing things, but, for me.... I get it done.....

I live in the Caribbean.
