I am currently reading advertisements of slave owners seeking runaway slaves. They are definitely a somber reminder of how African Americans were seen as nothing more than material possessions. Understanding the writing styles and vocabulary of the mid 1700's hasn't been too difficult but I have come across Nicholas Bearcraft's advertisement in "The Pennsylvania Journal" on June 8, 1749. He says his "wench" who is age 27 is often troubled with "Cholick." I tried to simply Google the word but all I get are a bunch of search results about chocolate. I doubt she had some sort of chocolate addiction so I searched for a variation of the word. "Colic" seems to be correct but everything is in regards to babies be blocked up or crying.
EDIT: I also thought there may be an off-chance she ran off with her baby and was troubled by her baby who has Colic but I am sure the slave owner would have mentioned a baby was with her. But then again all these advertisements are very vague.
It's indeed a spelling of 'colic', which is/was a general term for abdominal pain that's not very common now that modern medicine has come up with more specific diagnoses. Today 'colic' is often used as synonymous with baby colic or infantile colic, which itself is a more specific disorder.
