IF you can locate the 1869 Hungarian Census, it will giveyou the occupants of each house and their relationships. If memory serves me correctly, we couldn't locate the film number for anything but Lubisa.
If you see a marriage record and the age is over 30, you can be assured that it is a second marriage. That is usually noted (widow(er)) on the marriage record.
Sometimes you just keep on gathering data until you can finally fit the pieces together. Dates of birth were not very important in the old days but I WOULD trust the church records because they were usually written within a day or so of the actual birth. A problem arises with matching names, sometimes in the SAME house.
