Walter de Lasci is one of the earliest known progenitors of the De Lacy family. He accompanied William the Conquerer to England. One of his descendants, Gilbert de Lacy, helped with the Norman invasion of Ireland. The De Lacy family was a powerful family in Anglo-Irish politics. One of the numerous De Lacy descendants, James Lacy (b. 1828) immigrated to America in 1847. His descendants live in the United States. There are descendants of the original De Lasci who live throughout the world.

In this study, Moulton (social sciences, Johnson & Wales U.) describes the Russian military campaigns of 1719-1721 and examines their contribution to the ending of the Great Northern War. Drawing mainly upon 18th-century Russian-language primary sources, he assesses the military strategy of Peter the Great and considers the diplomatic and financial involvement of Great Britain on behalf of Sweden. Supplemental materials include a chronology, maps, and statistics for the Russian fleets. The text is based upon the author's doctoral dissertation (2000, U. of Denver).
