The following is an index to property transfer deeds and party wall agreements recorded at the Suffolk County Deed Registry from the original land purchase through December 31, 2020. 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.

 On July 10, 1882 (Book 1567, p. 33), the Commonwealth of Massachusetts conveyed to William F. Whitney a lot beginning at a line 110 feet west of Exeter and running west 20.5 feet to a line 130.5 feet west of Exeter.  All subsequent deeds for 228 Marlborough have stated that the northern and southern boundaries are 20.5 feet.

 However, on March 15, 1880 (Book 1520, p, 242; recorded 9Apr1891), the Commonwealth had conveyed to Samuel H. Whitwell a strip of land beginning at 130 feet west of Exeter and running west 6 inches to a line 130.5 feet west of Exeter. On March 25, 1880, Samuel Whitwell sold this strip of land to his brother, Frederick A. Whitwell (Book 1520, p. 245; recorded April 9, 1881), and on April 2, 1881, the Commonwealth conveyed to Frederick A. Whitwell a lot beginning at a line 130.5 feet west of Exeter and running west 24.5 feet to a line 155 feet west of Exeter (Book 1520, p. 246; recorded April 9, 1881).  All subsequent deeds for 230 Marlborough have stated that the northern and southern boundaries are 25 feet (the 6 inches conveyed by the Commonwealth to Samuel H. Whitwell and by him to Frederick A. Whitwell, and the 24.5 feet conveyed by the Commonwealth to Frederick A. Whitwell).

 The six inches running from 130 feet to 130.5 feet west of Exeter therefore is included in the lots for both 228 Marlborough and 230 Marlborough.
