How do I use Philadelphia marriage license index?
On the Philadelphia marriage license index https://www.familysearch.org/ark:/61903/3:1:S3HT-67X7-YSL?i=178&cc=1388247 what does the 4th column do for me? There is name, marriage date, sex and a number. Does this lead me to a more detailed marriage record? How do I use this info?
