Ol.
Ol. in old records is an abbreviation of the first name Oliver.
Ol. is a clerk's shortening of Oliver, given in name lists for English records. It is very short, so in poor handwriting it can be mistaken for an initial or a stray mark.
Look for Oliver written out in another record of the same family. An index may list Ol. as written, so a search for Oliver can miss it.
