Hi:
I'm not sure I understand the way you worded your query. Are you saying your birth mother's name was Lois Landis and that you were born with the name Constance Landis ... and none of these names are your adopted names? There is no Constance Landis born in all of CA on the date you mentioned or any other date in the state of CA (I checked the records every way I could).
Thanks, Terri
