In the records I quoted, the name appears to be Leo rather than David

With regard to nationality, the pamphlet I mentioned earlier ‘The Arabic Speaking People in Rhode Island’ has, in its introduction, an explanation re the Christian people who became known as Syrians.
The settlers in Pawtucket generally came from a different area than those who settled in Providence.
The descendants identify more through religion - Orthodox as Syrian and Maronite as Lebanese, for example.
That’s just my interpretation from the pamphlet and there is much more to read.
