While doing my research on the Healy family I found a Birth/Baptismal cert for a Cornelius Healy dated 8th June 1827. Address Dirriviclavoid in the Parish of Glenflesk. The correct spelling of the address should read as "Derrymaclavlode" His parents were Denis Healy & Margaret Murphy. I am not sure if this is the birth record of Cornelius Healy, father of Denis C Healy & children. I am still looking for a marriage cert for Cornelius Healy & Mary Sullivan Healy, possibly in 1854/55. These were famine years in Ireland and it is difficult to find out what parish they were married in.
I have no information on Mary Sullivan Healy and I have no photographs of any member of the Healy family.
Due to ill health I will not be doing any ancestry research for a few months.
I hope the above information is of help to you.
