...because of my ancestry searches I keep hitting dead ends because the woman's lineage disappears unless there is special care to record her family.

The main problem I have found in cases like this is the timeframe of the records you are looking at. I have run into this with an ancestor that died in 1867. I don't know her maiden name, but her husband was a pioneer settler in Ohio in the early 1800s. He had a very common first name for the time period and I am left trying to sort out who is who without good records.

So I think I am understanding what you are saying.

You are absolutely correct. The early census takers only recorded the name of who was the head of the house.... I am NOT in opposition to a man being the head. What has been totally frustrating is that the woman, the 'mom', if not the 'head' is typically listed by first name only.
