I am an Irish-American who studied Biblical Hebrew for a couple of years and who made a valiant but unsuccessful effort to learn Gaelic. I assure you, the languages are unrelated except to the extent all Semitic and Indo-European languages might be related. Both families have gender, number, case, and person. Adjectives agree with their nouns, and verbs agree with their subjects in some of these categories. Semitic roots are pretty obviously composed of three consonants, with vowels inserted at various positions to make the forms derived from those roots. Turns out that the earliest version of Indo-European that can be reconstructed, once Hittite is taken into account, also has triconsonantal roots. So it's possible that Semitic and Indo-European may ultimately be related, but beyond that Hebrew and Gaelic are unrelated.

I only meant that I thought it was interesting that the two groups seemed to have chosen similar sounds. I have only heard the two languages. I don't know anything about the vocabulary or the grammar of either language. (Other than a tiny bit about the origins and translations of family names and place names).
