It is generally a good idea to give some particulars when asking for help on this list. However, I did find information about a Margaret Brooks with the same general time frame who was married to a Mark Hilliard Jordan, a name on your list of managed profiles, so I am sending that in case it is what you are looking for.
The marriage of "Hilliard Jordan" (presumably him despite the absence of "Mark") to Margaret Brooks, age 20, is recorded as taking place in Hot Spring County Ark. on Nov. 28, 1940. Her parents are not listed there but she is stated to be from Malvern. You can see the record here: https://www.familysearch.org/ark:/61903/3:1:S3HY-XX8Q-DJ5?i=482&cc=1417439
The 1940 census for Hot Spring County has a Margaret Brooks listed in "Fenter Township outside Malvern City", enumerated on April 23, 1940. She is shown there as the daughter of James R. and Mary F. Brooks. https://www.familysearch.org/ark:/61903/3:1:3QS7-89M1-FFRN?i=52&cc=2000219&personaUrl=%2Fark%3A%2F61903%2F1%3A1%3AKQVY-22H
The 1930 census also lists as daughter to the same parents:https://www.familysearch.org/ark:/61903/3:1:33S7-9R4C-KVS?i=3&cc=1810731 and following page
The marriage of James R. Brooks and Mary F. Ross is found in the records of Hot Spring County as occurring on 18 May 1919. The ages of the parties are consistent with those in the censuses mentioned above. https://www.familysearch.org/ark:/61903/3:1:939Z-YFJF-M?i=300&cc=1417439
Based on the foregoing, it is safe to say that Margaret's parents, assuming this is the Margaret you are looking for, were James R. Brooks and Mary F. Ross.
