My previous post explored the origins of the “Peterborough Casbons,” a line that I’ve traced back to William Caseborne, who died at Littleport, Cambridgeshire in 1699. A chart outlined the first five generations of the family line, beginning with William and his wife Alice. The line of descent from William through the fifth generation is as follows:
1. William Caseborn (married Alice _____) → 2. Thomas Caseborn (baptized 1695, married Ann Kendale) → 3. Thomas Casborn (baptized 1732, married Mary Diamond) →
4. Thomas Casborn (baptized 1776, married Ann Dolby) → 5. Thomas Casbon (born about 1807, married Jane Cooper).
The following chart picks up where the previous one left off, beginning with generation five.
Although the chart begins with Thomas (born about 1807), I’ll start by going back to his father, Thomas Casborn (~1776–1855). Thomas’s line includes the only descendants of William Caseborn (generation one, died in 1699) who carry the Casbon surname today.
Thomas departed from Littleport with his family sometime between 1808 (baptisms of his children Elizabeth and Thomas) and 1812 (baptism of his daughter Sarah), when he was residing at Bluntisham, Huntingdonshire, some 14 miles southwest of Littleport. Thomas was the first member of the family line known to have the occupation of gardener.
Thomas’s only male child was also named Thomas, born about 1807 at Littleport (baptized 1808). He is at the head of the chart above. Thomas, also a gardener, is noteworthy as the first member of the family to live in Peterborough. I have written several posts about Thomas and his descendants. These can be accessed by clicking on “Peterborough” in the tag menu to the right of this post.
The Casbon surname would have died out in this family line were it not for just one of Thomas’s descendants. In the chart above, you will see that every member of the ninth generation was born to Charles Arthur Casbon (1880–1945) by one of his two wives. The family name did not continue through other family members due to a predominance of female offspring or absence of children born to any male offspring.
The line of descent from Thomas to Charles Arthur is as follows: 5. Thomas Casbon (born about 1807, married Jane Cooper) → 6. John Casbon (born about 1832, married Rebecca Ann Speechly) → 7. Thomas Casbon (born 1854, married Elizabeth Pettifor) → 8. Charles Arthur Casbon (born 1880, married first, Grace Parker; second, Eliza Kate Harvey; third, Ethel Wright).
Charles broke with the family tradition and became a baker instead of a gardener. He served as a horse keeper (groom) for the Army Veterinary Corps and rose to the rank of Corporal during World War I.
I have only limited information on Charles’s children, all of whom are now deceased. Joseph Arthur Casbon joined the Church of Jesus Christ of Latter-Day Saints and achieved a high position within the church. Leslie David Casbon was headmaster of a British School in Ethiopia and started the British International School in Cairo, Egypt. He was awarded the Member of the Most Excellent Order of the British Empire (M.B.E.) and later the Officer of the Most Excellent Order of the British Empire (O.B.E.), the latter presented by the Queen during a state visit to Ethiopia.
Although the chart ends with the ninth generation, William Caseborne’s descendants now extend to at least thirteen generations, many of whom now have the Casbon surname.
