The Aylesworth name is well-known to many of the Casbons who trace their roots through Porter County, Indiana. One reason for this is that Carrie Belle Aylesworth (1873–1958) was the wife of Amos Casbon (1869–1956). Their wedding took place on 28 November 1900 at the home of Carrie’s parents (see “Wedding Bells”) in Boone Township. This loving couple had six sons and three daughters, all but one of whom lived into adulthood and had families of their own. Many of their grandchildren are living today and remember them well.
Before Amos or Carrie were even born, there had been another Casbon-Aylesworth wedding in Porter County. That was the marriage of my second great-grandfather Sylvester Casbon to Mary “Adaline” Aylesworth on 30 October 1860. Sylvester and Adaline had two surviving children—Cora Ann and Lawrence—before Adaline’s untimely death in 1868.
Because of these two marriages, the descendants of Amos, Carrie, Sylvester, and Adaline are connected through both their Casbon and Aylesworth ancestries.
But what are those connections? How are the two branches related? The answer is fairly straightforward on the Casbon side. Their common ancestor was Isaac Casbon (~1773–1825) of Meldreth, Cambridgeshire, England, the grandfather of both Amos and Sylvester Casbon. Amos and Sylvester were first cousins, despite the fact that their ages were 37 years apart. Because of the age difference, their descendants of similar ages are mostly cousins “once-removed,” meaning their relationship to the common ancestor—Isaac Casbon—is one generation apart.
The connection on the Aylesworth side is more complicated. Carrie Aylesworth’s great-grandfather, Philip Aylesworth (~1793–1866) was the older brother of Adaline Aylesworth’s father, Giles (1807–1880). Their common ancestor was John Aylesworth (~1764–1810). Carrie was two generations farther away from John than Adaline; therefore, they were first cousins, twice removed.
The concept of cousins once or twice removed can be confusing, so I’ve created a diagram showing the lines of descent of the branches of the Aylesworth family to which Carrie and Adaline belonged.
The diagram also demonstrates the places where the Aylesworth ancestors lived as they slowly migrated westward to Indiana. This is an interesting story in itself and will be the topic of the next post.
The Aylesworth genealogy has been well-documented. Many of today’s living descendants have a copy of the Aylesworth Family book, last published in 1984. This book traces the family back to Arthur (generation 1). Most of the information about the first seven generations comes from an earlier book, Arthur Aylesworth and His Descendants in America, written by Homer Elhanan Aylesworth and published in 1887.[1] A copy of this book has been scanned and can be viewed or downloaded at https://archive.org/details/arthuraylsworthh00ayls.
Because of the Casbon-Aylesworth connection, members of the Casbon family have always been invited to the Aylesworth family reunions, which still take place on a (mostly) annual basis.
