Hello again Robert,
I am dying to find out as much as possible on the Jane Downing portrait at Cambridge.
The connection I find very interesting, is that it was lent by the Fullerton family.
The Fullerton's of northern Ireland were definitely woven into the Downing branch by virtue of the marriage of Dawson Downing, grandson of Adam, b. 1739, to his first wife, Katherine Fullerton on 3 Apr 1762.
Whether or not this was the "Jane Clotworthy" I am trying to prove remains to be seen, but your reference is very intriguing.
We are not even certain that Adam's mother was a Clotworthy. All that is known for sure, is that she was named "Jane" because he mentions her in his Will, dated 4 Jul 1716. It is presumed (but not certain) that Adam's father predeceased his mother and that his name was "Henry" as suggested by the book, "Genealogy of the Downing Family and Immediate Collateral Relations" by William Colwell Downing and R. Wilberforce, © 1901. William Colwell Downing was my great great uncle.
Another interesting fact, is that Col. Adam Downing (a Captain during the Siege of Londonderry), rode under the command of Col. Clotworthy Skeffington, 3rd Viscount Massareene, an association that may, or may not, have been arranged due to his father's marriage to Jane Clotworthy.
However, my research indicates that Sir John Clotworthy, 1st Viscount Massareene, had only ONE daughter, Mary, who married Sir John Skeffington, as you mention.
The first arrival I have found in northern Ireland of the Clotworthy's was (Sir) Hugh and his brother Lewis, who emigrated from Devonshire in 1573 with the 1st Earl of Essex under the Ulster Expedition. This is speculation and you have to believe the birth years for Hugh and Lewis given by ancestry.com (1563 - twins ?) for it to be true, but when they got there isn't important to this discussion. They were followed by an older brother, Simon, probably sometime after he married in 1582/3. Sir Hugh, knighted by King James I, was the father of the aforementioned Sir John and Lt. Col. James. James was seated at Muckmaire, County Antrim and Monnimore, County Derry.
Little else is known on James, Lewis, and Simon in my notes, so it would be of great interest to find out if Jane may have descended from one of those male Clotworthys.
As for Sir George, 1st Baronet; he was the son of Emanuel Downing and Lucy Winthrop and did indeed go to Massachusetts in 1638. However, as evidenced by family letters of Lucy (nee Winthrop) Downing, Sir George had no brothers named Henry or Nicholas.
Rev. Calybute Downing, Rector at St John Hackney, likely baptized all his own children and they are well documented. He had only TWO known sons, Calybute, who died age 6, and Henry, bp. 14 Nov 1640, as you state. The additional info you give on Henry is of interest but we have discounted him as being Adam's father because there is no Nicholas.
We know Adam had an Uncle Nicholas because he is mentioned as Co- Executor, in the Will of Nicholas Downing of Drummard, County Derry, dated 18 Feb 1698 and "Drummard" is just up the hill (perhaps adjacent) to "Rocktown", which Adam described as his homestead.
In other words, there can be no link between Sir George and Adam Downing, unless it can be tied into an earlier generation.
The bottom line and moral of the story is that we need to talk.
