The possibilities are pretty huge, given the extent of Kurdistan. You'd have a better chance of getting an accurate answer if you can narrow down the options, e.g. by including a suspected town (Paveh? Silemani? Rojava? Diyarbakir? Yerevan?), or providing any information about the language (Kurdish is really a language family, so the form of words that you or your ancestors remember might say where they are from, thus what "kalpatin" might refer to).

Well, I happen to have a Kurmanji dictionary, which would be the dialect most relevant for North Kurdistan, and I tried all of the reasonable variants but I don't see any Kurdish word that this might relate to. It is possible that it's Armenian Kurdish. It is reported that there was a Kurdish chiefdom in western Armenia
in Armavir & Aragatsotn provinces with the Kurdish name Qulp, Armenian Կողբ (Koghb), and extending into the Turkish town of Tuzluca. There is a 5th century writer from there known as "Eznik of Kolb". Armenian կողբացի is said to be from Old Armenian կողբացի [kołbacʿi] meaning "someone from the village of Koghb". However, current Koghb is much further north and east of the location of the "Qulp" chiefdom (but then, people move). So perhaps it relates to an earlier Armenian-Kurdish village.
