The answer to that question has been beautifully explained using the visual of a headstone:
Genealogy is found within the numbers carved into the headstone, and family history is found
within the dash. Everything that occurs between the numbers constitutes the story of who you are and how you got here.
I’ve heard people say that the past should stay where it is – In The Past. But as most of us discover – the past never stays put. It keeps creeping along behind us, showing up at places and in situations when we least expect it.
For example, about a year ago I received a message on my Ancestry account from a gentleman by the name of David Skelton, who was writing a biography on Professional Baseball Player John Bateman. He was wondering if there might be a connection between me and John. He had decided to contact me to obtain further information about his subject. I was a bit surprised, but as most who are familiar with me know, there's nothing I love more than a research challenge.
First – one good look at my family tree and you realize that you can’t spit without hitting a Bateman (I don’t truly advise spitting to see if you can find family—just so we are clear on that). After a few minutes of poking around, I discovered to my amazement that John Bateman and I were related and I was able to provide David with some family history anecdotes that related to that particular branch of the Bateman Family.

I guess what I am trying to get at is that Family History is, in essence, our story. It is filled with people, places and experiences that define who we are. It is the odyssey that has culminated in each of us—we are the treasure at the end of the quest --- Now, Let’s see just how we got here!
