MyFamily.com's new online subscription service has ruffled feathers in genealogy circles — particularly among researchers who've submitted family tree files to free pedigree databases on the MyFamily.com-owned sites Ancestry.com <www.ancestry.com > and Roots Web <www.rootsweb.com>.

OneWorldTree <trees.ancestry.com/owt/about.aspx>, the fee-based search engine Ancestry.com unveiled in June, links together all of the site's records and information about an ancestor. It uses a process the company calls “stitching” to find and combine probable matches so you don't have to weed through multiple databases and irrelevant results. An annual OneWorldTree subscription costs $49.95 ($39.95 if you're already an Ancestry.com subscriber).

The service has drawn genealogists' ire because it taps family tree data that thousands of researchers supplied to Ancestry World Tree <www.ancestry.com/trees/awt> in the spirit of collaboration. MyFamily.com also plans to include files submitted to RootsWeb WorldConnect <worldconnect.rootsweb.com>. (But that's “not at the top of the list,” says vice president of products Gary Gibbs.)
