He seemed to buy the story that his father was dead in True North, so I don’t think he has or will track down a father. Besides, Henry found Emma through a website ‘Whose your momma.org’ or something – that probably traced her from birth records. Since Henry’s dad (according to Emma) didn’t know about a kid, and I’m guessing Emma didn’t use his name on any of the paper work – there’s probably no way for Henry to track down his dad – but he probably wouldn’t anyway since Henry’s seems to believe his dad was a fireman who died saving a family.
