It is about the book that John wrote about William Mulvany who
is a relative of mine. The book is "Breaking Ground".
I visited John in 2003 in Germany and was last in contact
with him December 2006. However, since my return from Dublin in
2007 looking up more genealogical connections for the Mulvany
family I have been unable to contact him. His email
address I have is <firstname.lastname@example.org>. I have a letter
from him dated Jan 2003 but am unable to read his hand written
address which has changed from the previous one. It appears to
be Bert??????. 18, 50999 Koln. Would anyone be able to supply
me with his email address or home address or would you be able
to contact him and ask him to get in contact with me? I am related
to William Mulvany through my great grandfather Thomas John Mulvany
and for the past 10 years have been following up leads on various
family members who were resident in Dublin. John was a great help
to me taking me around the various sites in Germany where the
Mulvany brothers lived and worked. Because his book had
not been published at that time we weren't able to swop much information.
However I have a copy of the book and it has been of great assistance
I look forward to your reply.
