Bruce Ralston and I constructed a summary record of what we could both discover about the PILSON family or families that came from the general area of Hacketstown between about 1760 and 1890. My great, great grandmother and her ancestors were almost certainly members of this family. YOU WILL FIND THIS SUMMARY ON THE ANCESTRY.COM PILSON MESSAGE BOARD at
(If this address doesn't work, go to the PILSON message board associated with Ancestry.com and look at message #7, a message from Bruce Ralston dated 2/8/00 and headed Carlow.)
Bruce and my interests in the Irish PILSONs stops in the mid-19th century, when his family emigrated to Australasia and my great-grandfather was the last surviving member of my family with any direct contact to the PILSON family.
