Holland Land Company
In 1794 Hendrik de Clercq came to America to become a farmer. He settled in the town of Cazenovia, in the State of New York, because of his relations with the Holland Land Company (HLC). The HLC was an unincorporated syndicate of thirteen Dutch investors in Amsterdam, who placed funds in the hands of certain trustees in America for the purpose of investing in land in central and western New York State and western Pennsylvania.
Several of the thirteen investors were close relatives and friends of the De Clercq family in Amsterdam.

Lorenzo State Historic Site
John Lincklaen, the agent of the Holland Land Company and founder of Cazenovia, built a beautiful mansion on the shore of Cazenovia Lake, which he called Lorenzo. Lincklaen was married to Mary Ledyard, a niece and namesake of the wife of Hendrick de Clercq. Undoubtedly Hendrik and Mary have often frequented this house.
Lincklaen died childless in 1822, after which the mansion became property of the Ledyard family and it has been so for five generations, until 1970. Nowadays it is a New York State Historic Site
