It's a good question, and certainly something I wondered about. However, no narrative addresses this. All we can really do is lay out the known facts.

The Snowmen happens at Christmas 1892. Human Nature is 1913 — that is 21 years later. It's therefore easily suggestible that Captain Latimer could have remarried and had a son in the very late 1890s who could have grown up to be Tim. Or Tim could be a lateral relative, like a nephew or younger cousin.

The possibility of a relationship certainly exists. But it would be pure speculation to assert it as fact.
