The frequency and significance of women in Luke–Acts is generally recognized by interpreters. It is often suggested that this prominence of women is part of Luke’s overall strategy of inclusion of the marginalized. This is probably correct, but is interesting that while many women are named, there are also a number of women who are unnamed as can be seen in these two lists.
Named women: Mary mother of Jesus (1:14), Sapphira (6:1), Tabitha/Dorcas (9:36), Rhoda (12:13), Mary the mother of John Mark (12:12, 25), Lydia (16:14), Damaris (17:34), Priscilla (18:2, 18, 26), Diana? (19:24, 27-28, 34-35), Drusilla (24:24), Bernice (25:13, 23; 26:30).
Unnamed women: Paul’s sister (23:16), Pharaoh's daughter (7:21), Timothy’s mother (16:1), demon-possessed slave girl (16:16), Phillip’s daughters (21:9).
I am not sure what the ultimate significance (if any) of this is, but I did find it intriguing.
