Yes, it is named after Buffalo's fifth mayor Samuel Wilkeson.
Here is an excerpt from the Buffalo Rising article about the park's opening a few years ago: "The waterfront recreation site’s name comes from Samuel Wilkeson who was a member of the Buffalo Harbor Company that brought the terminus of the Erie Canal to Buffalo, versus its rival Black Rock. In the early 1820s, Wilkeson led the project to improve the harbor to make it suitable as the canal terminus. He served in the New York State Assembly, the New York State Senate and as Mayor of the City of Buffalo."
