Thank you Jean, I know that his age differs on a number of immigration sites. On Ancestry his age is shown as 18 and he certainly wasn't any older than that compared to his sister's age. We know how old she was when she came here in 1868, she died in 1888 after marrying my great grandfather James Fitzpatrick and having 6 children. Timothy died in 1886. I have considered that he may have gone interstate and have exhausted all avenues also that he may have returned to Ireland. Thanks for the suggestions.
