On the double surname issue - I agree with the previous post that the record is probably showing the father as having a double name, Ios-Shlioma. But that does not mean the record is correct. I have seen records for a town in Lithuania showing a relative's name as Refuel Michel, whereas his gravestone - and those of his children - all show his name just as Refuel. (He did have a son named Michel.) I recall an article in Avotaynu many years ago showing a similar issue, where names of brothers seemed to be combined into a single individual in 19th century Lithuanian records. This seems to have been common, so it becomes a question of trying to figure out which information is more accurate.
