Dear Abby, (couldn't resist)
Although I'm just a fledgling in the genealogy field, I would suggest that you explore BOTH spellings. The Soundex will come along later to do that in our Federal Census, which can often lead us out of the confusion associated with misspellings in transcriptions, "dialectical differences" and penmanship variations.
I suspect that you might prefer one spelling or the other, but keep your antennae up for both and consider that education and penmanship, as well as other factors, will be a spectrum. It is always possible to misinterpret (or overlook a valid source) if we put too fine a point on spelling.
Then follow the trails that both spellings have so kindly left behind.
I do the same for consonants as well, which led me to find my great grandfathers marriage certificate, handwritten in the period-correct penmanship, only by digging through the collected original documents and keeping an open mind.
