Martha A Cargil (Clack) - Connections

Her profile notes list her mother as Catherine Reno, but the mother connected is Sarah Hamilin. Additionally, her maiden name is showing as Clack, which doesn't fit unless she was adopted or is connected incorrectly.

I'm tracing a Hamlin descendan'ts line who is a DNA match to me. He has a Cargill grandmother on his Beavers line. However, if this Martha isn't the daughter of Sarah Hamlin, then either he has his tree wrong or Geni has the connections wrong, I don't know which.

I'm hoping someone can help me sort out if Sarah Hamlin is her mother. Thanks in advance for any assistance.
