Old English mearcere "writer, notary" (glossing Latin notarius "clerk"), literally "one who marks," agent noun from mark (v.). Not found again until late 15c., hence modern use is perhaps a separate formation. Meaning "monument stone" is from 1888. Sense of "tool for marking" is by 1725; meaning "felt-tipped marker pen" is from 1951, so called because their purpose was to highlight text.
