The following is an index to property transfer deeds, building restriction agreements, and easements recorded at the Suffolk County Deed Registry from the original land purchase through December 31, 2017.  Mortgages, trust agreements, and other similar recorded documents are not included.  This index is intended as a guide only; actual deeds should be reviewed for details.

Note: All deeds for 27 Hereford from the time the house was built through the deed dated September 10, 1980 (Book 9529, page 203) indicate the north-south boundaries as being 22 feet 3 inches. When combined with the dimensions of the other houses on this side of Hereford between Marlborough and Alley 429, this measurement results in a combined north-south width of the block of 112 feet, consistent with the original land deeds (Book 1458, page 250 and earlier). However, the deed recorded on April 14, 1994 (Book 19002, page 126) and all subsequent deeds indicate the north-south dimensions of 27 Hereford as 22 and 03/100ths feet, resulting in a combined width of the block of slight more than 111 feet 9 inches.
