Duggan

Hi. i am looking for family of Dennis Duggan born 1809 in tipperary, he married mary cummins 15/02/1836

i have information on all the female children and one of the sons John who married hanora sadlier. im looking for Patrick Duggan born 07/12/1836, Mathew Duggan born 17/01/1839, Denis Duggan 13/02/1846 and William 16/04/1852. if anyone has any information on these it would be great, i know William erected a headstone in memory of his dad Denis, mother Mary and sister Catherine. His mother Mary died in 1906 so it must have been done some time after this, i think most of them emigrated.

thanks
