Pennsylvania Marriage Records?
Yes, Philadelphia marriage records are available and indexed. It depends, a little, on what time period you are looking for where and how you will find them.
If you want to share details, I can walk you through the process to find them. Feel free to send me a private message (click on my username to see the option to send me a message) if you don't want to post here in the Community or if anyone mentioned might still be living.1
