These are not friend requests (at least I don't think so,) they are notifications from FB itself suggesting new friends. They are all young women, about 30 years old, and most of them are in other countries.
I have no personal info whatsoever in my FB account, everything is locked-down private, and I have no friends. (the only reason I have a FB account is because some businesses and my local homebrewers club live in that space instead of having a www website)
