WOLFEBORO, N.H. (AP) -- Every year, Mitt Romney and his family spend a week at his estate on a picturesque lake in New Hampshire.

They go boating, play games - and attend church, an expression of the faith that's fundamentally shaped the Republican presidential candidate.

Romney, the first Mormon to clinch the presidential nomination of a major party, attended services Sunday with his wife, Ann, five sons, five daughters-in-law and eighteen grandchildren.

They made up nearly a third of the congregation at Wolfeboro's branch of the Church of Jesus Christ of Latter-Day Saints. The Romney clan has attended the church there many times before - only now the family patriarch carries the distinction of being President Barack Obama's challenger.

Romney plans to spend the week in Wolfeboro.
