Query Re Mchugh Family Dunfanaghy Donegal Ireland

Thank you for taking the time to read this and perhaps be able to help me in my research. i am trying to find information (I have some but very little),on The family of John McHugh and Mary Duggan,of the above location All I have is the date of theirmarriage on 01 Jan 1854 in Dunfanaghyplus a bit about their son ,Hugh's life ,once he immigrated with his brothers to Australia this was inthe late 1800's. What I really would like is if someone had information about thier lives in Ireland and any thing else they feel would be relevant to this country.
