Samuel Boardman's book about the Boardman descendants gives John's a birth date of Dec 14, 1829 in Newmarket, New Hampshire and we find John in the 1850 census in Lowell prior to his marriage working as a manufacturer.
By 1860 we find John and Mary in Andover, Mass with three children: Henry G, Charles W, and Ida L. where he is working as a machinist but he moved to Concord by 1867 where he worked as an overseer of a carding room and lists his home in Fisherville that year when he was exalted into the Grand Royal Arch Chapter of New Hampshire.
By 1870 the family has grown significantly - the census lists John working as a life insurance agent with property value of $2,500 with children Henry J, age 15, Charles W, age 12, Alice, age 10, Fred, age 8; Burt, age 6, Mary, age 4; and Frank age 1. We believe that daughter Ida L is living with Mary Jane's sister Clara Batchelder in Massachusetts.
The early 1870s show John living at Valley near Forest in Concord working as a life insurance agent working for Phoenix Mutal Life Insurance Company out of Hartford, Connecticut but by 1877 he is listed in the City of Concord Annual Report as a city pauper who received $14.00 from the city and by the 1880 census, the children who are not old enough to be living on their own are either in orphanages or living in other family homes working as servants or laborers. We have not found an 1880 census listing John.
Our next record of John is a record of his death on September 22, 1892 at the age of 62 in Lowell. He is listed as widowed although his wife Mary Jane was still living. His cause of death was due to paralysis -- we do not know when the paralysis occurred nor what caused the change in the family's living situation in the 1870s.
We think we found Mary Jane in the 1880 census in Concord with her youngest son Harry Shackford, age five but that census oddly states that this Mary Shackford was born in England and the father of Harry was born in Canada. We suspect that she was trying to hide from authorities but she or someone from the family had to answer the door when a census taker showed up so they made up the responses. We do know that Mary Jane started working as a nurse in Concord in the 1880s and moved from Valley to 59 N Spring in Concord, then to 18 Pearl St. In 1900, we find her with son Alfred Laurent in Worcester, Massachusetts on June 1, 1900 and on June 8, 1900 at the Old Ladies' Home on 96 Pleasant. Both censuses state that she had eleven children, ten of which were still living (he eldest son Henry was the first child to die). Mary died on April 2, 1901 at the Institution Home for the Aged in 1901 of a cerebral hemorrhage. According to city records, the city of Concord or her estate paid $3.00 for her burial at the Blossom Hill Cemetery.
