My Greatgrandfather was Owen Mcsherry. He had a sister Catherine who lived in Leitrim and was married to Cormick meehan. There may be a connection. He and his 2 sisters Ann and Bridget moved to Scotland while 3 others migrated to USA..
I dont know if this is the same family, but Owen Mcsherry was from Leitrim. When in Scotland the Mc was dropped and they became Sherrys'
