What did Robert LaSalle do to leave a legacy

Searching for the Mouth of the Mississippi i think

Required to reject his father's legacy when he joined the Jesuits, La Salle was nearly destitute when he traveled as a prospective colonist to North America. He sailed for New France in the spring of 1666.[6] His brother Jean, a Sulpician priest, had moved there the year before. La Salle was granted a seigneurie on land at the western end of the Island of Montreal, which became known as Lachine.[7] (This was apparently from the French la Chine, meaning China. Some sources say the name referred to La Salle's desire to find a route to China, though the evidence for this claim is unclear and has been disputed.)

La Salle immediately began to issue land grants, set up a village and learn the languages of the native people, mostly Mohawk in this area. The Mohawk told him of a great river, called the Ohio, which flowed into the Mississippi River. Thinking the river flowed into the Gulf of Mexico, La Salle began to plan for expeditions to find a western passage to China. He sought and received permission from Governor Daniel Courcelle and Intendant Jean Talon to embark on the enterprise. He sold his interests in Lachine to finance the venture.[8] In 1682, he named the area Louisiana after King Louis XIV of France.
