Question

Uncle Tom
Do we have to capitalize the word Uncle Tom？
Like the sentence, We are planning to visit Uncle Tom's home today? Or, we are planning to visit uncle Tom's home   today?

Answer

You do, because it is part of his name. It's a title, like Mr, so it has to be capitalised.

You'd say:

I'm going to visit my uncle.           = here it's an ordinary word, so it's a small 'u'
I'm going to visit Uncle Tom   =  here it's part of his name, so it's a capital 'U'
