In all my research on Esther Morris I found no place in legal documents or family references showing her middle name as Hobart. My belief is that she was given that middle name after her death, celebrating her illustrious Hobart ancestry.
I now refer to her as Esther Morris. She was born Esther McQuigg and following her two marriages she was Esther Slack then Esther Morris. With today’s way of showing a woman’s maiden name as her middle name (as I do) she will be Esther McQuigg Morris.
