Requesting help from any surname experts.
I have recently been given access to my Father's family tree and amongst the names I came across a very unusual surname - Sector. I have tried many internet searches, worded in various ways, but the search engines keep bringing up search results based on the word sector (business, science) and not related to it as a surname. I would be interested to learn of the origins and meaning of this name. It is very far back in my Father's tree, and there are no current relatives with this name.
Thank you, in advance, to any person willing to help me with this.
