Like most people who get hooked on genealogy, I’m attracted to the detective work aspect of the enterprise. A clue here; a detail there; another hint here, which, combined with a few previously discovered clues and details, finally provides a solid lead; and then: bingo! a nice little nugget of documented and verifiable information, which may then serve as a clue for some other discovery; and on (and on!) it goes.
It’s very easy to overlook a relevant detail, though.
