There may be a connection since Camila's Harringtons were in the Great Maplestead area and Pebmarsh is a neighbouring parish so its quite possible. However, I think there are quite a lot of Harrington families in that area and there's no guarantee they are all related. One of Camila's ancestors is believed to be a member of the Castle Hedingham and Sible Hedingham Elliston family, albeit there are missing PRs which would confirm her link beyond any doubt. Two other Harrington's married into that family, although whether they are related I don't know. My interest is in the Elliston family because my own Elliston line is Suffolk is known to be related because of some bequests in a early 1600s Will to Elliston kinsman from there, but the exact relationship is not known unfortunately.
You'd probably need to extract all the Harrington's in the area and see where each belonged to be of any certainty unless someone gets a mention in a Will. Unless of course someone else has widely researched the family.
