I found several Bellingham's but I don't know if you can use them. I found an Alan Bellingham born c.1517- 78. There are several more including Edward Bellingham b.c 1545-1605 of Putney, Surr. and Woodmancote and Ovingdean, Surr. also Henry Bellingham b.c 1564-1637 - Chichester,Suss.
William Bellingham - b.c1755-1826 of Coleshill,Herts.
Alan Bellingham b.c.1656 - 93 of Levens,Westmoreland.
There are several others and also some other information that it is too numerous to write. However, the site that you may need is the
www.historyofparliamentonline.org. I hope this will help. And if you need any other help. send me a message thru wikitree. Thanks, Nancy
