Wilmington Trust, a unit of M&T Bank, was sued by heirs to Mennen Co., maker of Speed Stick deodorant, seeking more than $100 million in damages for investment losses.

Mennen, based in Morristown, New Jersey, and sold to New York-based Colgate-Palmolive in 1992 for $670 million, was founded in 1878. A descendant, George S. Mennen, set up a trust in 1970, according to formerly sealed court papers in Delaware Chancery Court in Wilmington.
