Maybe it's time for Who Do You Think You Are? to be renamed How I Met Your Parents.

Shares of Ancestry.com (Nasdaq: ACOM) soared 11% yesterday on reports that the leading genealogy website operator is about to put itself up for sale.

A source "with knowledge of the situation" is telling Bloomberg that the company is working with Frank Quattrone's Qatalyst Partners to weigh the matter and smoke out a buyer if it decides to go in that direction.

The speculative buzz comes nearly a month after the stock got crushed when Comcast's (Nasdaq: CMCSK) (Nasdaq: CMCSA) NBC Universal revealed that it will not be renewing Who Do You Think You Are? -- the primetime genealogy series that finds Ancestry.com helping celebrities dive deep into the roots of their family trees -- for a fourth season.

Bloomberg's source indicates that the buyer will likely come from the ranks of hungry private-equity firms, and that seems about right.

An analyst in the story offers up that Google (Nasdaq: GOOG) and Facebook (Nasdaq: FB) would also be logical suitors, but neither party makes sense.

For starters, Facebook can't be interested in Ancestry.com because it's very profitable and generates gobs of revenue. Yes, that's a lame Instagram joke. Seriously though, what would Ancestry.com add to Google of Facebook? Google would be more likely to blow up the premium model in favor of a more far-reaching, though potentially less lucrative, free ad-based genealogy solution. Facebook is also perpetually battling the silly rumor that it will begin to charge its more than 900 million active members to use the site. The last thing it needs is to add fuel to that nonsensical fire by buying a site where you have to pay to gain access to research tools.

Private equity is what really makes sense if Ancestry.com goes through with this. Ancestry.com is a strong and growing company. Revenue and earnings climbed 19% and 50% respectively in its latest quarter. This is truly a scalable model, and a well-heeled investor that can continue to grow this company -- out of the critical sight of a finicky market that triggers a sell-off over a show's cancellation or baseless accusations that the model will be disrupted -- is the best course for the company.

Ancestry.com has good genes. Maybe now it can find someone to take advantage of that, but it won't be Mark Zuckerberg or the fine folks at Google.

Ancestry.com has been a disappointment since I recommended it to Rule Breakers newsletter subscribers two years ago, but a few big winners have been more than enough to generate overall market-thumping returns for the growth stock service.
