When searching, bear in mind that most of the transcribed passenger
lists have been sourced from old newspapers, these can be difficult
to read and the original author may have used a spelling different
from that which you might expect (i.e. Smyth instead of Smith).
First names were often abbreviated in early newspapers due to space
limitations... so when William doesn't turn up, try Wm. as well.
Common abbreviations were: Jas., Alex., Wm., Jno., Edw.
