Quick & very belated note re B'haalot'cha confusion

This is one of those interesting challenges that the Torah occasionally presents:

Numbers, chapter 10 (from Parshat Behaalotecha/B'haalot'cha (whatever)

כט  וַיֹּאמֶר מֹשֶׁה, לְחֹבָב בֶּן-רְעוּאֵל הַמִּדְיָנִי חֹתֵן מֹשֶׁה, נֹסְעִים אֲנַחְנוּ אֶל-הַמָּקוֹם אֲשֶׁר אָמַר יְהוָה, אֹתוֹ אֶתֵּן לָכֶם; לְכָה אִתָּנוּ וְהֵטַבְנוּ לָךְ, כִּי-יְהוָה דִּבֶּר-טוֹב עַל-יִשְׂרָאֵל.	29 And Moses said unto Hobab, the son of Reuel the Midianite, Moses' father-in-law: 'We are journeying unto the place of which the LORD said: I will give it you; come thou with us, and we will do thee good; for the LORD hath spoken good concerning Israel.'

If, as I've heard, Chovav/Khovav (Hobab) is another name for Yitro (Jethro) and Reuel is also another name for Yitro, who is the person named here?  Is Chovav the same individual as Yitro, or is he the son of Yitro?  Personally, I'm inclined to think that this is Yitro's son, just because Yitro would have been pretty old, if even still alive, at this point in the story.
