The already big Cowsill family adds one more member in June when Bill Cowsill, 20, gets married.
Cowsill's future bride is Karen Locke, 19, a student at Visual Arts School in New York City. Originally from Allentown, Pa., Karen met Bill three years ago while she was visiting Newport, Rhode Island, home of the singing family. The two have been dating ever since.
The wedding is scheduled to take place in Newport at the end of June. The entire Cowsill family is reported to be delighted with the news.
