You might have heard a conjugation of the verb 'shikaru'(to scold), like 'shikarare mashita'
which would mean '(I,you,etc) was/were scolded'.
It has a weak possibility to be two words of shi and kara in which case it could mean 'from death', 'since death', 'from the corpse' and such.
You might have mistaken 'chikara' (power, strength) with shikara.
Maybe you heard 'shikaraba' which means 'if that's the case, if so'.

If you are asking what the Hiragana means, then I would say it doesn't mean anything, except for 'Caitlin,' because names are the same in every language. The name 'Caitlin' is pronounced 'Keitorin.' Names in Japanese tend to be written in Hiragana, which is a form of Japanese writing, rather than Kanji, which is the form of writing that is most commonly known. The Hiragana for 'Caitlin' is 'ケイトリン' Hope that helps.
