The house at 170 Water Street, on the west side of Wadawanuck Square in Stonington, was built in 1833 for Sarah Potter Denison Palmer (1785-1862), a decade after the death of her husband, Luke Palmer (1775-1822). Known as the Widow Luke Palmer House, it was described as follows in Grace Denison Wheeler’s The Homes of Our Ancestors in Stonington, Conn. (1903):
The Widow Luke Palmer’s house is one of the old landmarks although none of the older residents seem to know when this house was built; still it is known that Mr. Palmer married Sally P. Denison in 1804, and they lived there. She used to board the men connected with building the Stonington Railroad, Mr. Almy, Mr. Matthews and others, about 1835. The house has been so added to and improved that but little of the original can now be seen. It was owned by Mrs. William L. Palmer, and her heirs sold it to Mr. Henry Davis, whose heirs sold it to Miss Emma A. Smith, and in 1901, the Roman Catholic Society purchased it of her. At various times three clergymen have lived here: Rev. M. Willey, first Pastor of Calvary Church; Rev. R. S. Wilson, Pastor of the Baptist Church, and Rev. A. G. Palmer, who was so long the good minister of the Baptist Church.
