Yes, that's the passenger record we are working from, and we have assumed the same thing about Mary being Michael's sister. Glad to get another outside opinion on this. I have found a baptism record in Scotland for Rose Murphy for right about the correct birth date from St. Andrews, Glasgow ... child of Michael Murphy and Marg Linnan (thought maybe this could be a misspelling of Leonard/Lenard/Linnard). We're pretty confident we have the correct passenger record, and have all the census records from 1860 on, along with military records, etc. Thank you again for all your help. It makes me feel much better to see that others are seeing the same evidence that we are.
