I can't find them on a passenger list (yet). I don't know whether there are any that aren't listed on the UK departure lists though.
There is a possible death for James Wickham Jul-Sep 1914 Wexford age 65. And for Alice Wickham Apr-Jun 1929 Wexford age 82.
Going back a little bit, there is an Edmund Loftus Wickham who died Oct-Dec 1891 age
75 in Limerick, so maybe they are all related to him?
And now I'm getting confused - I also found an Edmund Loftus Wickham on the 1901 Irish census age 12, in County Limerick, son of Eugene Alexander and Helen.

And still there in 1911 (again, no Frank with the family):
