It is believed that the vault was built by John I. Slingerland and William H. Slingerland when patriarch John A. Slingerland died in 1850. John A. was initially buried behind his homestead located at 1575 New Scotland Road, Slingerlands, NY. In 1851, the family voted to move John A. to the new vault.
This is an extract from John I. Slingerland's 1851 cash book, which resides in the historical archives of the Town of Bethlehem.
The following heirs agreed to have my father John A. Slingerland deceased taken up where he is now buried and have him removed and buried where the marble monument now stands with his inscription on.
Leah Slingerland for to take up
John I. Slingerland [ditto]
Wm H Slingerland [ditto]
F. B. Slingerland [ditto]
E. Vanderzee [ditto]
T. Ten Eyck Waldron agrees to do as the above.
Albert Slingerland and Hester Loucks are opposed to have him taken up.
In 1852, the vault is completed and inscribed
FAMILY VAULT OF
JOHN I. & Wm.H.
ERECTED A.D. 1852
