NEW YORK, Nov 4 (Reuters) - Spectrum Equity Investors-backed website Ancestry.com Inc (ACOM.O: Quote, Profile, Research) priced its initial public offering of 7.4 million shares at $13.50 per share on Wednesday, within the expected range.

Ancestry.com, which operates a website that allows people to trace their family roots by scouring online records, will begin trading on Nasdaq under the symbol "ACOM" ACOM.N on Thursday.

The Provo, Utah-based company had expected to sell 7.4 million shares in its IPO for between $12.50 and $14.50 each, in a $100 million offering.

Ancestry.com, which said it had 1 million subscribers as of September, was founded in 1983 and is majority owned by private equity firm Spectrum, whose stake in the company will fall to 54.8 percent after the IPO from 67 percent. Spectrum bought Ancestry.com for $354.8 million in December 2007.

The existing shareholders are selling about 45 percent of the shares in the IPO, with the rest coming from the company.

Ancestry.com expects net proceeds of $48.4 million from the IPO, and will use the money in part to repay $12.1 million it owes CIT Lending Services Corp, a unit of CIT Group Inc, (CITGQ.PK: Quote, Profile, Research) and use the rest for working capital.
