I say in my bio that my ancestors came from Wales. While Woodbury is a Saxon name, my umpteenth great grandfather, William Woodbury, self-identified as a Welshman when he came to Salem in 1628. I discuss the origins of the name ‘Woodbury’ and its Welsh possibilities here: http://www.sarahwoodbury.com/about/the-origins-of-the-name-woodbury/
I am also descended from a host of Morgans, Thomas’, Kemries, Johns, Rhuns etc. The line I’ve researched most successfully descends from Llywelyn ap Ifor born around 1300. Six generations later, Sir John Morgan (1448) was knighted and is featured here: http://tredegarhouse.blogspot.com/2006/05/sir-john-morgan-7.html
One of his sons, Thomas, married Elizabeth Vaughn and had Rowland (who became sheriff in 1588). The line then goes Henry-Thomas-Robert to Samuel, who had two children: Anna and Robert. Anna, born in 1685, married Hezekiah Ober. Their child, Joanna, married Elisha Woodbury, 8 generations up from me through my father. In turn, Robert married Mary Thorndike. Their son, Paul, is also 8 generations up from me, through my mother.
In addition, a reader was kind enough to inquire about my ancestry and explained that Llywelyn ab Ifor’s wife was descended from Rhydderch ab Iestyn, whose father Iestyn is thought to be another son of Owain ap Hywel Dda. The line from Rhydderch comes via his grandson Caradog ap Gruffudd. Caradog married Gwenllian, daughter of Bleddyn ap Cynfyn, King of Powys and later also of Gwynedd. Llywelyn ab Ifor’s father, Ifor ap Llywelyn, married Tangwystl, who was the daughter of Rhys ap Hywel ‘Sais’. The father of Hywel ‘Sais’ was Rhys ap Gruffudd, The Lord Rhys, Prince of Deheubarth. (So it goes: Lord Rhys – Hywel ‘Sais’ – Rhys – Tangwystl). Llywelyn ab Ifor’s grandfather, Llywelyn, married Nest, daughter of Hywel ‘Felyn’, Lord of Senghenydd, son of Gruffudd ab Ifor ‘Bach’, Lord of Senghenydd whose wife was Nest, daughter of Gruffudd ap Rhys and sister of The Lord Rhys ap Gruffudd.
He explains that this is yet another example of how dynastic lines became entwined, which makes many Welsh people kinsmen. It also (particularly in the example of Rhydderch ab Iestyn) provides a better sense of how battles between various lines began, each claiming some inheritance from a common ancestor.
This is the family tree of the Kings of Wales, also very much a matter of intertwining lineages: https://en.wikipedia.org/wiki/Kings_of_Wales_family_trees
