My great grandfather’s birth record

A few years ago I found the below “birth record” on Ancestry. It is for my great grandfather. However, Ancestry doesn’t have the images, and FamilySearch has the images, but no index. 

The problem with browsing the images is I’m pretty certain this isn’t a birth record. The title of the database is Hungary Civil Registration 1895-1973. 1861 is not in that range. However my great grandparents were married in the late 1890s. The marriage records do provide dates of birth, places of birth, and parent names. I think Ancestry created a birth record from a marriage record. Why they don’t have the marriage record in their database I’m uncertain. It’s possible the record page was damaged in some fashion and the bride’s information was not legible. It’s supposition until I find the record. 

So I browse the marriage records, right? They’re divided by location, naturally. I did look at all the Vitka marriage records. I can’t read the Hungarian, but it’s not too difficult looking for the names on each document. The record wasn’t there, so I suspect my great grandparents were not married in Vitka. So what town were they married in?

I don’t know. That’s the problem. And there are a lot of towns in the database.

My great grandmother was born in Margitta. She doesn’t turn up in the Ancestry search, and there are no Margitta records in the FamilySearch database. I suspect they were married in some town nearby one of their births. 

I did search for the birth records of my grandfather and his siblings - without success. I have a copy of my grandfather’s birth certificate which he had in his records. But I don’t have that for his siblings. I also searched for the record of death for one of his siblings. Browsing through the images I couldn’t find the town of Nagyalmas where they were born. Those records may not have survived. 

It would be really nice if FamilySearch could index this database. 

Or I have a lot of records to browse through.
