Little Baddow is a village in Essex County, England. It is near to the county town of Chelmsford, and is very close to Great Baddow. Nowadays it is largely a commuter village, but until relatively recently it would have been an agricultural-based community.http://en.wikipedia.org/wiki/Little_Baddow
Peacock is a relatively common name and there are at least 2 if not 3 or more well developed families in Essex. I know this as I have Peacocks in my own family and am Essex-based yet often stumble on other Peacocks with no known tie in to my tree (including the Baddow Peacocks).
The Peacocks of Baddow are shown on ancestry in dozens of UK census records. There are many records of them on the IGI/Mormon site at:https://www.familysearch.org
