Hi Isobel - just in case you don't have the info, the two newspapers are:
The Westmeath Examiner and the Longford Leader. Both have contact details on their website.
http://www.ardaghdiocese.org/page10.html gives the details of the parish priest. He may still have the original registers,if you are lucky. As it happens he is covering both St. Mary's rathowen and St. Mary's Street, (which is a nearby village).
It might be worth sending him a copy of the letter too.
Russagh is very close to the Longford Westmeath border. Street or Streete is the next village to Rathowen, so right beside Russagh. Parts of the area intrude into Co. Longford.
If you have looked at Shanes link, you will get the idea.
Local historians John Tormey and Peter Wallace wrote a book about Russagh in 1983.
If you don't have this book, PM me and I will be able to give you a contact address.

McGoven John Russagh Westmeath
And for Street:
Mc Govern Patrick Kilshallow Street Westmeath
is the only likely family listed - either could well be Michael snr's father/brother/uncle, but you need proof to link them.
