Hi Dathai, I finally went back to Glasnevin this week and spoke with the lovely and helpful Lynn who gave me a printout of all interred in the Lynch Family grave for 8 euro of course, for which i was delighted to have its packed with vital info.
I also went to where the Family lived after Lavina returned to Dublin it is in Temple Crescent Blackrock.
it was strange seeing it for the first time and my research told me that there was a name on the gate which reads "Warriwee" this confirmed the correct house,
sadly I have not been able to contact any of John and Lavina's three children whom I met at least twice. they were born in the 1930s i understand.
they may be dead I don't know. I am aware that R Chat don't allow info on living relatives.
best regards
Gerald
