I wonder if that is only because they spy on us? Hmmmm how to find it. Well I tried mine. Did not come up. So I googled Himpton. Just Himpton and first entry is Holder. Wondering if someone is planting that info and why.
Think it more has to do with the weirdness of one’s first and middle names. And here in the east, it’s more common for a middle name to be derived from a surname rather than from a first name. And that also tends to make names either more unique, or show up as a family unique name set. Of course, then middle names migrate into first names. My favorite surname migrating name was Livingston Livingston.
