I know a Holman who may have some info that may be useful to you. If you would like to message me directly through ancestry.com I can give you her email or phone number.
She mentioned that there are 2 Holmans directly from Scotland and had a land grant in the 1700 or 1800's but there is a gap after that. Same gap you hit maybe. If you email her , she will be happy to share with you any information that will assist you.
