Hi, When checking Ed Finn's 1901 Census Leitrim-Roscommon Database at his website, be SURE and check for your surname of interest under both "head of household" and the "other occupants" category. I found several Co. Leitrim households with the name of Cornyn, many with connections to Co. Cavan. As well, I came up with even more when I entered Cornyn into the "enumerated with" field who were living with families with other surnames as relatives and servants. Many were from Co. Cavan, one girl was born in Co. Louth. Bottom line, you might find your ancestor living with another family in a completely different county. Nothing ventured, nothing gained.... Jean
