Where does 見当もつかない come from?

見当 first meant the direction you aim at: Nihon Kokugo Daijiten (via Kotobank) quotes it from 1830 for a target missed, and from the Jinkaishū law code (1533) for an estimate. The Daijisen also lists a printer’s register mark, the guide that shows where the paper goes. So not being able to fix your 見当 is like having nothing to aim at.

Mistakes learners make with 見当もつかない

Using it for a fact you simply don’t know, like someone’s name. It’s about not being able to estimate or work something out, so for a plain gap in knowledge 知らない is more natural.
