How do you properly find out about your families history/lineage/tree?

by PM_For_Help

A co-worker told me about how his families history led him to find out he could apply for citizenship in another country. Apparently, a friend of his researched his family for him to get the info. This got me thinking about researching my history.

How does one go about learning where they come from and family history in general?

Hi, your question is fine here, but the sub that specializes in family history research is /r/genealogy. Do consider x-posting over there for some tips to get started.
