Hi Judy, I am also glad to see some more interest in my surname.
I am looking for William Carscadden, but my search is in Canada. However I am
open to a new avenue (of-course) and will check what you have sent.
On the name Carscadden, one reason you may be havinbg trouble in 1800.
According to Edward Maclysaght, former Chief Herald, Ireland-'he knows of no
reference to it (Carscadden) before the beginning of the 19th century." It is
supposed to come from Scotland, but the name was "Garscadden"
It is not a common name and the margin for different spelling is high, (my
thoughts).
Good Luck in the 1800's and please let me know if you find the name as I am
getting close to the 19th century.
Sincerly, Paula Carscadden
