This is an uncommon surname, sometimes (even less commonly!) spelled HOLLILAND; in the past there were various other spellings but those are the only two that survive.
I run the registered Holyland One-Name Study so have lots of information about holders of this surname, going back into the 1500s. If anyone comes across this surname, or versions of it, in their tree, I'd be interested to hear from you and may well have info that you would find helpful! So please leave a message!
