Welcome to the Allardyce site.There is another great place you must visit.It is Allerdice.net
I think that all of us of the Allardyce name hailed from Scotland at one time or another.I know that my direct line immigrated from Aberdeen Scotland in the 1700's.We have our tartan and all of the other regalia that goes with Scottish pride. In fact, there is going to be a worldwide Allardyce/Allerdice, etc. reunion in Oct. of this year in Atlanta, Georgia, at Stone Mountain.(That was the place of one of Dr. Martin Luther King's speaches).I think that you would enjoy it.All of the info is on the Allerdice.net site.
I look forward to hearing from you and hope that you will share your genealogy with us.
