Irish Culture/Origin of name
Shea is my middle name and am aware it is a masculine name of Gaelic/or Celtic origin meaning "hawk-like; admirable". I learned it comes from the name "Seaghdha". I recently learned that it is also of Hebrew origin and means "supplanter" since it is apparently is another form of Sťamus. Now Sťamus is Celtic, the Gaelic equivalent of James. So now I have two names that Shea could come from (Sťamus and Seaghdha) yet the names are seemingly unrelated. Now are these two names somehow a variation of one another with different meaning depending on origin or are they completely different and it just so happens you can get the name "Shea" out of both of them?
Since 'Keegan' is one of my family names, it would seem to me that your middle name is derived
from 'O'Seaghdaha', which is indeed Gaelic for "stately". We do not find it in the lexicography
for 'hawk', which is of course 'seabhac'.
Have never run across 'Shea' as a short hand form for 'Seamus', which is indeed 'James' in
The Hebrew for 'James' is ya'aqov, so I think we can conclude that the derivations and meanings of
'shea', vis a vis Gaelic and Hebrew, are separate and distinct.
With best wishes to you for a Happy New Year.
