Maggie Pearl (Benbow) Davis

The census records for 1920 and 1930 show daughter Nellie and her family living with Dennie L and Maggie. The 1920 census shows son Denny P Davis living with them; the P stands for Paul, and some records show that as his name.

Margaruite Is a non-standard spelling but that is what’s on her grave marker. Her death certificate says Margret. More common would be Marguerite and most common Margaret. "Maggie" works for all.

A DIFFERENT Margaret. The following two census records show a Margaret/Maggie who was married to Elijah Joseph Lambert. Elijah and his children are incorrectly linked with this geni record for Maggie Benbow, but really it's some other Margaret (Margaret Jane Wich 1885-1971 https://www.familysearch.org/tree/person/details/L8SQ-Z5V). These census records are included here to show they conflict with the above census records showing Maggie remained married to Dennie Davis.
