First name needed for a female serial killer

I’m thinking about working on a story about a [name_m]Black[/name_m] Widow who kills her husbands and some of the children, but I’m having trouble with her first name. The story would be set in early 1930’s [name_u]Philadelphia[/name_u] and she originally comes from a poor family. She is 33 years old at the start of it and I’d like her middle name to be [name_f]Louise[/name_f].

The other family members are:

1st Husband [name_m]George[/name_m] [name_m]Franklin[/name_m] [name_u]Kelley[/name_u] (51. A carpenter)
[name_m]Alexander[/name_m] [name_m]Raymond[/name_m] “[name_u]Alex[/name_u]” (16)
[name_f]Clara[/name_f] [name_f]Beatrice[/name_f] (15)
[name_m]Frederick[/name_m] [name_u]Michael[/name_u] “[name_u]Freddie[/name_u]” (12)
[name_f]Rose[/name_f] [name_f]Elizabeth[/name_f] (10)
[name_f]Lillian[/name_f] [name_f]Charlotte[/name_f] “[name_f]Lily[/name_f]” (7)
[name_m]William[/name_m] [name_m]Theodore[/name_m] (6)
[name_m]Thomas[/name_m] [name_m]Vincent[/name_m] “[name_m]Tom[/name_m]” (4)
[name_f]Florence[/name_f] [name_f]Katherine[/name_f] “[name_f]Flora[/name_f]” (3)
[name_f]Emma[/name_f] [name_u]Jean[/name_u] (1)

2nd Husband [name_m]Charles[/name_m] [name_m]Robert[/name_m] [name_m]Langston[/name_m] (48. A police officer)
His sons [name_m]Walter[/name_m] [name_m]David[/name_m] (17), [name_m]Samuel[/name_m] [name_m]John[/name_m] “[name_u]Sam[/name_u]” (13), and [name_m]Louis[/name_m] [name_m]Andrew[/name_m] (11)

3rd Husband [name_m]Milton[/name_m] [name_m]Horatio[/name_m] [name_m]Thorpe[/name_m] (62. An architect)
His daughter [name_f]Helen[/name_f] [name_f]Josephine[/name_f] “[name_u]Josie[/name_u]” (9)

Give her a name that could have caused her to grow up with a low self-image. If she came from a poor family, think of low-income names. The name could have contributed to her becoming a murderer.

I’m for giving her the most normal name ever. Like [name_f]Mary[/name_f], [name_f]Jane[/name_f] or [name_f]Anne[/name_f].

If you want a name with a dark meaning, [name_f]Lilith[/name_f] means night monster and sounds kind of old fashioned. But otherwise, I’d go with [name_f]Dolores[/name_f], [name_f]Beth[/name_f] or [name_f]Bethanne[/name_f], or maybe [name_f]Emily[/name_f] (it means rival, which kind of fits).

I agree with @Nerdynamegeek - [name_f]Lilith[/name_f] has the perfect meaning, and goes well with the middle name [name_f]Louise[/name_f]. I’d go for a name like that that has a dark meaning and fits with the chronological period.
