Learn English – Which tense should be used

The expression you want is

I was born and raised in India.

Both verbs are completed actions, so they are expressed in the past tense. "Raised" means that you spent your childhood there, and is neutral on the issue of whether you are currently living in India or not. You could also say "brought up" instead, but "born and raised" is a more convenient expression.

Incidentally, a related expression is

I'm Indian, born and bred.

That has a slightly different meaning. To be bred means to be brought up in a specific way, so this sentence means that you have very strong characteristically Indian habits due to being brought up there. This sentence is also neutral on the issue of where you currently reside.

It should be 'was married' - I'm not sure of the custom in India, but in my experience, marriage (like most earthly institutions) ends when either party passes away. Indeed, Christian wedding vows make explicit reference to this with the line "Til death do us part".

I suppose his wife could still consider herself married to him, but that would be a personal thing. Once one party to a marriage is dead, so is the marriage.
