Hello. I'm a Jameison whose forebears came from the UK, Jamaica WI, and NYC in that order.
Please read my posted replies on the message board of FamilyHistory.com for more insight. I hope it gives you at least some info. You might be surprised at what you read....but tell me...were any of your Jameison's immigrants from England by way of the British West Indies??
Hope to hear from you soon.
