What are two facts about William Clark?

William Clark was born in the late 1700's. He married and had 10 children. He knew Meriwether Lewis from working with him in the White House. His older brothers name was George Rodgers Clark and his other brothers name was Johnathon. His parents names were Ann Rodgers and John Clark. He had 7 sons named Jefferson Kearny, William Gilbert JR., Meriwether Lewis Clark Sr. ( not the person he traveled to the passage way to the pacifc ocean with.), William preston, George Hancock, Julias Clark, and Edward Clark. He had 2 daughters named Mary Margret Clark and Harriet Clark. Whoever wrote this past answer is the stupidest person in the history of the world bcuz it states that William had 10 children then later it says he had 7 sons and 2 daughters. Excuse me but i am pretty sure 7+2=9. ... just saying! :{
