Mister
Madam, Miss, Mx
suffix
The kanji means family name because it goes after a family name in very formal situations. So, it's really closely tied to that. Because only men got the respect back in the day, we're calling this vocab word mister. You can call me Mr. Koichi if you'd like, too.
The reading for this word is the same as the kanji.

ベッカム氏

ビル・ゲイツ氏はシアトルの生まれです。
Mister Bill Gates was born in Seattle.
田中氏は、いつまでも来ませんでした。
