The claim specifies a $16 million price point for a double-wide Gilded Age mansion near Prospect Park. While multiple web search results discuss expensive Gilded Age mansions in Prospect Park (e.g., $12.2 million, $12.49 million), none of the provided evidence sources corroborate the specific $16 million price point or the specific listing mentioned in the claim. The evidence is limited to general market reports and other properties.

The claim contains multiple specific details (one of three designed by Gilbert, part of Park Slope Historic District, only one retaining single-family status) that are attributed to specific listing brokers (Thomas Handschiegel and Mackenzie Kyle). While the general context (Gilbert designing multiple structures in Park Slope) is supported by the evidence, the specific claims about the number of structures, the historic district status, and the unique single-family status are not independently corroborated by the provided sources.

The claim provides a specific measurement (32 feet wide) and a comparison (average 15- to 20-foot-wide). This specific detail is not independently corroborated by the provided evidence. While the concept of the townhouse being unusually wide is implied by the context of the listing, the exact measurements and comparison figures are unique to the claim's source.

Multiple web search results independently confirm that the first owner was George W. Kenyon, an industrialist, and that he was a Harvard classmate and early supporter of Theodore Roosevelt. This specific biographical connection is reported by multiple real estate listing sites/articles.

The claim states that Kenyon's company manufactured military uniforms for WWI soldiers. While the evidence confirms that defense contractors exist and that militaries use uniforms, there is no specific evidence linking George W. Kenyon's company to government contracts or WWI uniform manufacturing.

The claim makes a specific historical claim about the number of families (only four) that have owned the residence since construction. No evidence was found in the provided sources to confirm or deny this specific ownership history.

The claim provides specific, sequential asking prices ($12.78 million, $14.75 million, $15 million in 2024). While the evidence confirms that properties in the area have had varying asking prices over time, the exact sequence and amounts listed are unique to the claim's source and are not independently corroborated.
