"Anderson County Gleanings Vol. 2" by Dorothy Lickteig -
Information taken from an obituary for Mary Jane "Jennie" (Cassidy) Sargent.....sister of Thomas Cassidy.
Jennie Sargent (Mary Jane Cassidy) died July 29, 1924. She was buried in the Emerald Cemetery, Anderson County, Kansas. Jennie married Hollis Sargent on Aug. 3, 1869. Jennie was borm in Edinburgh, Scotland on January 26, 1853. She was the 9th child of Anthony Cassidy and Mary Jane Doolin Cassidy.
Jennie had 8 brothers - Patrick, Michael, John, Maurice, Thomas, James, Anthony, Jr. and Matthew.
James Cassidy died in his teens.
After the death of his wife, Anthony and Matthew emigrated to the U.S. and both died in the Civil War.
The other brothers stayed in Scotland.
The emigrants settled in Pennsylvania, later Missouri, then Paola, Miami County, Kansas.
Personal comments: It would appear that of the children of Anthony and Mary Cassidy, only Mary Jane, Thomas, Matthew and Anthony, Jr. came to America. Matthew and Anthony Jr. dying in the Civil War. And Mary Jane and Thomas being buried in Anderson County, Kansas.
Hope this helps,
