Re: Clavins in ND, SD, Ontario (?)

I´am looking for my roots in Ireland, my greatgreatgrandfather was Thomas Clavin born near 1819, he was married to Margaret Feeney born in 1834 aprox. They came to Argentina perhaps in 1865 or 66, we belivedthey were cousins of the Kelly`s. My other greartgreatgranfather was Barny Langan (from Horsleap) married to Ann Ward who was de daugther of Owen Ward(1800-1871) and Mary Browne (1800-1886).If you know something about them, please call me by e-mail as soon as you could. .
Many thanks
