<human>: I know this might not be the best sub, but askreddit just removed my post, and I don't know where to ask this.

A little background, my family immigrated to US 10 years ago, and my mother have met a really good friend. He helped us with many things, he had bought a car for my mother cause he knew we were struggling back then. 

He works oversea a lot, and we would get dinner together every couple month. But two years ago, we realized it had been over a year since he returned our calls (we were friends for at least 7 years back then). We tried to find him, and see if he is okay. He is in his early 60s, and we know he had some health issues.

The hard part to find him is my mother DOES NOT remember his last name! Nor have we met any of his family members before. We tried sending a note thru his house, and no one responded to our note. This happened in 2012-2013, my mom just mentioned today again, and it hit me that I might be able to get some insight from you guys. (I was young back then, probably could made this really easy if I had a brain, I could probably checked the yellow pages and found his name).

So right now:
I know the company where he works at, but it is 10,000+ employee size.
I know his first name, but not the last.
I do not have his address anymore, is been so long.

Is there anyway can find his status? I really just want to make sure my mother and I can visit his grave if he is not alive anymore. If he is alive, then I know there must be a good reason that he can't contact us anymore.

I wanted to contact the company, but I don't want to come up as suspicious person snooping around their employee. Please help us, he is our first good friend in a new country, and we really want to just know about what happened, and not ever regret about it later in life.

Can you condense the text into three sentences or less?
<bot>: Want to know if old friend is alive or not, does not have his last name, how should I find him?
