If you use ancestorsonboard there is a George K Fyfe, born in 1900 who sailed from Saouthampton to NY in 1947, plus 6 other G. Fyfes. 3 Ediths, 1 born in 1906, two in 1917 (probably the same person) are recorded, the second apparently making two voyages in 1948 and 1951. You need to buy credits to get the full details which I do not intend to do but, unless you are absolutely sure these are not the people you are looking for it could be worth it.
