Did Katalin DEUTSCH nee SONNENFELD change her name to DERI

Sadly I kdo not have the Information...

There are about 4 questions in one here.

Firstly, I cant find any evidence that Katalin Sonnenfeld born 1835 and wife of Ignac Deutsch ever changed her surname to Deri.
Nor is there any evidence of her husband having done so either.

Now their kids
I could find no record of any person called Heinrik Dozsa-Deutsch
A Henrik BIRTH NAME Deutsch born 1866 however did change his surname to Dózsa in 1896, married a Roza Böhm, lived as Henrik Dozsa thereafter and was buried as such.

Next
There does not appear to be any person called Alexander Deri-Deutsch either
The Roza Reichenfeld in the tree was married to a Sandor Deri (NOT an ALEXANDER Deri-Deutsch) and had a daughter Eva and not EWA

Unfortunately submitter of the profiles must be unfamiliar with how a hyphen should be correctly used, for linking the birth name with the new name without a space, suggests the individuals lived the remainder with a hyphenated name, and there is no evidence to support that.

Thanks, I will update and add the sources to the profiles.
