There isn't a single, universally accepted Gaelic spelling for "Taylor." Gaelic (both Scottish Gaelic and Irish Gaelic) doesn't have a direct equivalent word. The translation would depend on the meaning intended. "Taylor" refers to someone who makes clothes. Therefore, you would need to find a Gaelic word for "tailor" and then translate that.
To get a suitable Gaelic spelling, you'd need to consider which Gaelic you're interested in (Scottish or Irish) and then find the appropriate word for tailor and transliterate it. This often results in different spellings and pronunciations depending on the region and dialect.
