I would love to see more information on Mary's parents and the information on them. They seem to be what might be the connection with John L's father, Michael. Names, birthdates and places, church records, etc. I know a lot of people who get records online but don't have the primary records to back up those. Maybe you could get your sister to respond here? Since she has done the research, I'd love to "pick her brain" and compare information.
