The Lansingburgh Historical Society (LHS) does not, by and large, have genealogical research files on specific people or families.
LHS does have some resources, or may be able to point to some, that may be of help to those doing genealogical research.
A list of LHS records on long-term loan to the Rensselaer County Historical Society (RCHS) that are publicly accessible in the RCHS library can be seen here: RCHS LHS manuscript collection. Lists of vertical files and books that are at the Melville House are in the process of being updated.

In searching censuses, keep in mind that Lansingburgh was part of the Town of Rensselaerwyck from 1788 to 1791 (thus for the 1790 US Census) and then part of the Town of Troy from 1791 to 1807 (thus for the 1800 US Census).
FROM 1771 TO 1875.
[1819 – Town of Lansingburgh annexes area from Lansing’s Grove to Grant’s Hollow from Town of Schaghticoke]
[1836 – City of Troy annexes Batestown from Town of Lansingburgh]
From 1771 to 1815 the population is estimated. From 1820 it is the complete Town Census, and subject to a deduction.
