He married Tillie in Ohio 10/1/1901 (the two Davidovitz brothers married the two Wertheimer sisters!). He had a hotel in McKees Rocks at the time. Seems pretty clear he was married to her for the rest of his life, what with both couples always living together, &c. This guy is surely not who was married to Hermina.
1914 passport application says moved to Cleveland in 1902 (though I believe there is a 1903 Pgh-area newspaper mention for him).
[Martin Davidovitz = Martin Devay! We know that Martin Devay was in the Pgh area since quite early, but was it this guy? First city dir 1892. Says Braddock 1894. Devay bought seats 1901. Never in cash book, tho. Need to figure out basic facts about him like when married?]
