Have you explored familysearch.org? I am sure there would be tons at this site which you could learn from. It's an amazing database.
Because I am limited by information, I am unable to confirm any question asked within your post but I can say that there would be more than one Eleanor. Perhaps the one which you search for would be a descendant herself?
Also, because I am unfamiliar with countries outside of the US categorize cities/counties mapping, I could not venture to guess if one place would be physically to another (ie:changing boarders because of city growth, regional conflict, or a family simply deciding to move a mile or two down the road, but changing regions in the process)
I have found that family names repeat heavily. Not only paternal but maternal as well. Not only do that repeat, but often times, I have found that many have been given a name at birth but then called another through life-- which translates to another name on the census and registrations of the era-- and these names vary with spelling. It also seems there are lots of children named after siblings-- which adds to the confusion, but is often a good sign because it increases the likelihood that they are within the group you are searching.
