01. Robert Burnham ^[1] was born about 1581 in Norwich, England.  In 1608 he married Mary Andrews (1585-1635).  They had 7 children.  Two of their sons, Edward and Benjamin remained in England.  He died in 1608. 

02. Thomas Burnham, ^[1] son of Robert and Mary was born in 1623 in Norwich. 

"The 3 Burnham brothers, John, Thomas, and Robert, sons of Robert and Mary [Andrews] Burnham, arrived in May, 1635 on the ship "Angel Gabriel" in the charge of their maternal uncle, Capt. Andrews, master of the ship. Capt. Robert Andrews, was the brother of Mary [Andrews] Burnham. The ship :Angel Gabriel" pulled into Pemaquid Bay (Pemaquid, Maine) on August 13, 1635 and laid at anchor. The next day there was a terrible rain storm which ravaged the whole coast from Nova Scotia to New York starting at morning. The Angel was torn to pieces by the savage storm and cast away. Most of the cattle, 1 seaman and 3 or 4 passengers died. The others escaped to shore. Among the few personal belongings saved was a chest belonging to the Burnham boys. The tides had been as high as 20 feet. Some passengers set up tents along the shore and John Cogswell [Coggswell] went to Boston and sought the help of a Capt. Gallop who commanded a smallbark, or barque as it was called then. He took some passengers to Ipswich and made another trip the end of October. The 3 Burnham brothers went to Chebacco, in the colony of Massachusetts Bay, probably with their uncle, Capt. Andrews, and John Cogswell and his family in Capt. Gallop's barque."
