Hi Annie
i m researcbing Islay almost daily and islay familly names continued to be handed down
for a long time specially where large groups of Islay folk moved at the same time which seems to be
the case in my own familly, and when looking at emigration to Canada i ve noticed that large groups
of 20 and 30 where paid for by only one person either it was assisted passage or it was familly groups
all related in some way ie cousins inlaws paying via an agent,
i believe this to be the case with Marlins familly, looking at the census years for those i know to be her familly there consistantly appears a close link to other familly surnames from Islay ie Gilchrist,
MacArther all on the same census pages, unfortunately emigration to Canada from Islay pre 1865
isnt greatly recorded,
the way i look at is brick walls where made to be knocked down and it can be rewarding doing it
so don t give up.
