Capt. Samuel M. Bailey, 83, a former waterman who founded trucking, seafood and resturant businennes in St. Mary's County, Md., died Thursday at St. Mary's Hospital in Leonardtown. He had cancer.

Capt. Bailey -- the captain was a courtesy title dating from his days as a waterman -- was born at River Springs, Md., which is now called Bushwood. He was a lifelong resident of the town.

In 1914, he founded Bailey's Express Co., a trucking firm that is now run by one of his sons, Bernard. In 1929, he went into the oyster business and in 1957 this was incorporated as Capt. Sam's seafood, a general wholesale and retail seafood supplier. He also started a restaurant, The Seafood Place, in Waldorf. The seafood business and the restaurant now are run by another son, Samuel M. (Bo) Jr.

Capt. Bailey himself remained active in these enterprises until his death. He also was a former director of the First National Bank of St. Mary's in Leonardtown.

He was an Army veteran of World War I who served in France and was a member of American Legion Post No. 221 in Avenue, Md. He was a charter member of the Optimists Club of the 7th Judicial District, which covers part of western St. Mary's County, and the sponsor of amateur baseball and softball teams in the area.

Capt. Bailey was a member of the parish of the Holy Angels Catholic Church in Avenue.

His wife, Mignonette Cullins Bailey, died in 1963.

In addition to Samuel M. Jr. and Bernard Bailey, both of Bushwood, survivors include a third son, Edward, also of Bushwood; three daughters, Catherine Swann of Bushwood, Eleanor Tippett of Avenue and Lucille Farr of Maddox, Md.; one sister, Sister Catherine Elizabeth Bailey of Newburgh, N.Y.; 21 grandchildren, and 19 great-grandchildren.
