Is it correct to say below sentence?

I hope one day all our family can gather in one place together.

I dropped "of" because it doesn't go with "family". "Hope" establishes the conditional without the help of "could", and so "could" seems redundant. You hope a factual thing. You don't hope a might-be.

Thank you so much for your quick and concise replies. Can I also ask you that is it correct to say:

How is your dad? Please give my regards to him.

Perfect.

Thank you very much again. I promise this is my last question dear enoon. In this sentence:

I would like to tell you that recently I have became an uncle.

Is it correct to use Have with became? and should I use recently after "I" or before "I"?
