Dear Susan, I have been talking to you through emails and a couple of telephone calls a few years back however this recent happening has occured and has proved vital points. However I have discovered my Great Great Grandfather Michael Hanlon had a twin sister Anne. At the time of the 1901 and 1911 cenus there were to sisters living in the same townland called Eliza and Anne which were his to sisters that I have just discovered. However I done a search of the parents and a further two children were found their names were Patrick/ Peter who were twins. So this means that their parents Michael Hanlon and Mary Ann Doran had two sets of twins and one daughter. Have you come across this in your search. My email is firstname.lastname@example.org
if you wish to discuss this any further.
