I think they swam
because I'm not having any luck finding an arrival for Patrick Lynch (b.1832, Ireland d. 1891, NSW) his wife Bridget nee McGraie/McGrail or his children Mary (b. 1856, Scotland?) and John (b. 1857, Scotland?). I have a marriage record for 1855 in Scotland and a birth record for a daughter Annie in 1859 in Wellington NSW but between that... Yeah. They swam.
