Alexander Sándor Kende (Wolf) - Kende/Wolf Name Change?

Are there any sources for a Wolf to Kende name change?

I’m looking for anything to show that Samuel Wolf and Alexander Kende are the same person. The only link I can see is that there is an index (szatmar.us) for a marriage certificate between Ida Markovic and Samuel Wolf. But this could mean that Ida was previously married to Wolf or there could be an error in the index. There is no access to the actual marriage certificate.
