Do you ever wonder if your family name and linage is untrue?

I was just thinking of this recently.

My family name goes back 900 years back to Scotland. The story is that after my ancestor helped hide the rightful Scottish king from a usurper, that king later retook the throne and gave that answer a lordship and land that my family name comes from.

I was thinking about how there was probably 30 to 40 generations from that ancestor to me; it makes wonder if along the line a wife of someone in my family tree had an affair or was otherwise forced impregnated with another man, if that’s true my name would be illegitimate.

Do you ever consider that possibly you might be descended from an affair.
