John Britton, Jr., was born in Dumfries-shire, Scotland, and was keeper of Customs at Ballyshannon, County Donegal. Both of his parents were from Scotland.
John married Alicia Orr and they had several children including Rebecca Louise who was born in County Donegal. John and Alicia didn't have a daughter Catherine or a son Thomas.
I would like more information on the other children, who according to Tammy Hoherz, were Frances Jane Bean, Johnson, Helena Kerr, James, Robert, and Dickson. John, Jr.'s mom was Margaret Dickson from Scotland.
Tammy believes Margaret Dickson and Alicia Orr were both descended from Alexander Fergusson and Annie Laurie, but I found no evidence to support that claim. Some of Annie (Laurie) Fergusson's descendants are listed in www.thepeerage.com.
