Check out this wonderful site. Here you can find a brief bio of most personalities in Scripture.
The About page.
Here is an example:
אִישׁ בֹּשֶׁת בֶּן שָׁאוּל (אֶשְׁבַּעַל) (שמואל ב ב, ג, דברי הימים א ח:לג )
A son of שאול . After שאול dies, his loyal general אבנר crowns איש בשת king over Israel. איש בשת however, loses אבנר ‘s support after accusing אבנר of sleeping with שאול ‘s concubine רצפה בת איה . איש בשת is forced to return his sister מיכל to דוד after she had been given to פלטי בן ליש . After אבנר ‘s death, איש בשת is killed by his own men בענה and רכב who cut his head off and bring it to דוד . This angers דוד who has בענה and רכב killed. איש בשת is buried in the grave of אבנר . In דברי הימים he is called אֶשְׁבַּעַל .
