Yesterday, I examined the Rhodes family with Holden Rhodes Sr. being the family mystery. Very little information has been located on him thus far.
A second case is the Jennison family.
Robert Jennison, the immigrant, was from Colchester, England. Some of the details are sketchy. His birth, about 1606-1615; date of arrival, 1630-1637; date of marriage, about 1639. From the time Jennison was made a freeman in Watertown  until his death on 4 July 1690 at Watertown, local records tell his story.
Ensign Samuel Jennison spent his life in Watertown. Local records give a nice accounting of his community service, birth, marriage, death and family.
Robert Jennison's story lacks the fleshing-out that exists for his father and grandfather. He called Watertown, Cambridge, Framingham and Auburn home over 95 years.
Joseph Jennison has a birth and death date, but little else to tell his story.
Peter Jennison, who saw action at Lexington Green, has a few details to flesh out his life over 66 years.
Dolly Jennison's story is told mostly through her children. An exact marriage date is lacking, but birt and death dates are given.
