There's an interesting text available on the web at
http://www.antonymaitland.com/ (go to the "Chadwick" family).
It's a book called "The Chadwicks of Guelph and Toronto and their Cousins",
written by Edward Marion Chadwick, and privately printed in 1914 in
Toronto. One of the families documented is the following:
----
WILLIAM CHADWICK, of Ballinard, "Billy Snug," born 1741, died March, 1825.
Married firstly, November, 1767, Christiana Carden (sister of Sir John
Craven Carden, Baronet), second daughter of John Carden, of Templemore,
County Tipperary, and his wife Elizabeth, daughter of Rev. Robert Craven
and his wife Rose Otway. She had a marriage portion of £2,500 secured on
Ballinard, Illanemeene and another estate. She died February, 1782.
He married, secondly, in 1793, Sophia Carden, only daughter of John Carden,
of Barnane, and his wife, Anna Sophia Roe, a cousin of his first wife; she
survived her husband and died September 1825, aged 82.
----
So this guy was married to both a Templemore and a Barnane Carden. Several
descendants have "Carden" as a middle name.
Note that the illustration showing the Carden and Craven arms has the
identification switched.
In the introduction, the author acknowledges the considerable help with
searches of one Mr. Philip Crossle, "who claims a sort of cousinship
through the Cardens". One assumes he is a relative of the Rev. Charles
Croslegh, who researched the Killard branch of Cardens about the same time
this work was being done.
