Billings, Mont. • Surveys show that many people who visit Yellowstone National Park hope to see wolves.

Park interpreters annually talk to anywhere from 30,000 to 50,000 people a year about wolves.

But a Montana biologist provides a way for wolf enthusiasts to learn the lives, pedigrees and genealogy of the wolves.

Jim Halfpenny is founder of the Yellowstone Wolf Genealogy Family Tree.

The Billings Gazette reports (http://bit.ly/2rFhoNL) that Halfpenny started recording the lineage of Yellowstone's wolves when they were first reintroduced to the park in 1995 and 1996.

The information is available online at http://www.wolfgenes.info as well as Ancestry.com.
