Sorry if any of this comes across hurtful or upsets you.
If this is someone you knew in life but recently passed on, I'm sorry for your loss, but don't try and hold him to the mortal realm. When people die [working on the theory there is an afterlife] their spirit is reborn, or goes to a 'heaven' depending on the faith. Sometimes they stay behind, but if he has, he would be somewhere that he loved [with his wife and child] spirits with a reason to stay usually remain with loved ones or their home. Some do wander the earth, but they normally died suddenly or refused to let go. As well, a spirit might remember its name in life but if we are reborn it has many lifetimes, and a spirit who was male in life could identify female in death which makes your inquiries that much more difficult. Many spirits I have met who are just wandering from place to place usually don't have a name or don't remember. I've only met two spirits who introduced themselves by name, and one was a departed family member who remained in her old home where the family still lived.
If you know the spirit and wish to try talking to him, you could try a divination method to get in contact. Set up an altar [table] with their photo and a few items of his [say a wedding ring, his cologne, favourite shirt] then try contacting him by name. You could skry with a black mirror, crystal, or bowl of water, use a pendulum, or simply ask a question and meditate to receive an answer. You could also use a Ouija Board but I would hold off until you've tried all other options. He might of crossed over, while sad, be happy he was fulfilled in life.
