I am not researching this ALDEN surname, but saw a post about a George and son John from Southampton, England. I hope this can and will be able to help some ALDEN researchers.
I have a book called, "Southampton in 1620 and the Mayflower," Held in the Maritime Museum, Southampton, July - September 1970, by Southampton City Records Office.
page 7. "One new member joined the emigrants in Southampton, John Alden, a tall, blond, and very strong young man of twenty, who was hired as a (now page 8) cooper to look after the indispensible water, beer and other store in barrells and boxes."
page 8. ...."There was at least one family called ALDEN going back to the 15th century, and one George ALDEN, a fletcher (arrow maker) by trade, is known to have lived and worked in the town from 1587 to 1620. The last recorded mention is of him claiming 20 pounds (worth about 1000 pounds in modern money) from Hugh and Ellen Russell in the Town Court in May - July 1620, the last date of all being 6th August N.S. (27th July O.S.) If he died between 6th and 15th of August (when the Pilgrims sailed) and it seemed unlikely the debt would ever be recovered a 20 year old son might well choose to try his luck in this new adventure." ...."A cooper like John Alden with no dependents would be an obvious person to press, and might well choose to escape by going with the Pilgrims.It is very unlikely we shall ever know for certain if John ALDEN was a Southampton man, but if he was the son of George then he would have had been born about 1599 in a house in High Street whose site today is part of Owen Owens store."
page 13. "Rate Roll for part of All Saints Parish, 1602. The site of George Alden, who was possibly father of John Alden the 'Mayflower' Pilgrim, can be discovered by this Roll used with other documents as a check. It can be shown from these that he lived on part of the site of the modern store, Owen Owens. His name appears as the thirteenth one down on the list" [Rate Roll list].
(Note: the town of Southampton was a Walled town, and marked off in numbered 'lots')....BTW, William Shakespeare was also of this town of Southampton in the same time frame..
page 30, LOT Number 18. No. 18 House of George Alden, Fletcher. "This is the probable site (about modern No. 174, part of Owen Owens store) of the house of this man who was quite likely to have been the father of the only "Pilgrim Father" who joined at Southampton - young John Alden the cooper".
