Dear Ms. Greve,
Thank you for posting your request on History Hub!
We suggest that you contact the New York City Health Department for assistance in answering your questions regarding corrections and indexes to New York City birth certificates in 1924, and the Form 6-H.
We hope this is helpful. Best of luck with your research!
I would get in touch with New York City Health Dept. but at the moment they are working on COVID. I am not sure if they have time to answer these questions. I attempted to ask these questions from them a few years ago and did not get much of an answer. In fact they gave me no answer to the above questions. I thought it would be a good place for me to come to find out an answer to these questions. I do wish that they New York City Health Dept. was a little bit more accessible. The Archives are a lot better to deal with.
