Hi,
I can answer the bit about Addison Baker Cresswell and his link to his John Addison.
John Addison was baptized on 11 May 1725 @ Easington in Cleveland, Yorkshire, England. He married Elizabeth Cresswell at Woodhorn, Northumberland 17 Jun 1767.
John's sister Jane Addison baptized 27 Sep 1720 @ Easington in Cleveland, Yorkshire, England married Francis Easterby (senior) on 5 Jun 1746 @ Easington in Cleveland, Yorkshire, England.
Their son Frances Easterby (junior) baptized 26 Dec 1761 Whitby, Yorkshire, England marries Frances Dorothea Cresswell who was baptized 18 Jun 1768 at Dorking, St-Martin, Surrey. Frances Dorothea is the niece of Elizabeth Cresswell.
They were married on 6 Dec 1787 @ St-George, Blumsbury, Camden. In 1787, John Addison dies and Francis (junior) his nephew inherits. Francis & Frances Dorothea's first son was baptized 26 Oct 1788 at St-George, Blumsbury, Camden and named Addison John Easterby.
in 1807, Francis buys out Grace my 5th great grandmother and becomes Francis Cresswell and Addison John Easterby becomes Addison John Cresswell.
Addison John Cresswell marries Elizabeth Mary Reed on 25 Jun 1818 at St-Giles, Camberwell, Southwark. When her cousin John Baker dies (date?) Addison inherits on condition he takes the Baker name. He then becomes Addison John Baker Cresswell.
Hope this helps with the confusion of the names
