Mary Susan Lucass (Davis) - How Does Mary Susan Davis/ies Have the name Lucass?

I don't know why, nor do I see how it's possible for Mary Susan Davis to be known as Mary Susan Lucass.

She married Thomas Doyle in 1933, aged 46, and if I have the correct Thomas he was a widower when he died.

My research suggests that Mary may have even died in 1934 the year after their marriage, but that is inconclusive at this moment.

Thomas seems to have had a Son Named Joseph at the time of his death. But was it from Mary?

Maybe I have the wrong Thomas' Death and the wrong Mary's Death? In which case anything is possible.

She may have re-married if Thomas died first.

Of course it may be that someone is a big Star Wars fan and the name was added subconsciously. :)
