According to a Slattery family group sheet on file at the Fairfield Public Library Louise was born in Prussia. Where she died isn't stated.
Father was Valentine Roth (don't know where he is buried, yet). Mother was Kathrine E Roth, (a/k/a Katherine Elizabeth Stauffombiel per a Slattery Family tree on Ancestry). The mother's DOB and DOD differ somewhat between that Slattery family tree listing and the F/A/G memorial. Will link to her, but with that caution.
