Is this method of avoiding putting a ? for a hard to read letter legal?
I am reviewing United States—Enlisted and Officer Muster Rolls and Rosters, 1916–1939 [Part J][M37X-625]
Instead of using a Question mark to replace a letter that could be one of several choices the indexing person has made an additional entry for the individual (Martin T L?hman) entry 19 & 20. Is this a legal solution?
