My experience with some of these marriage records is that although they asked for the maiden name of the mother, many times you get what the current surname is, and that could be a name obtained after a re-marriage. That is what I suspect for SILVIA ROBINSON. They also sometimes listed the current wife of a remarried man as the mother for the bride or groom, rather than the actual mother if the mother was deceased. Here is Silvia's census in 1880:

Sylvia may have been a MAYO/MAYHO herself, in which case she was free, however, she apparently didn't know her parents birthplace. Some of the MAYOs in Warren came out of VA after 1850, which is why more seem to appear about 1860, but Silvia said she was born in NC, so you may want to see if you can find her in NC prior to this. I have a family of MAYO/MAYHOs from Halifax Co.,NC all descended from Granville MAYO & Mary Jane EVANS, and I know there was another group in Granville Co.,NC, one of which was another Cuffee MAYO, b. 1815 & his wife Glatha Ann HAWKINS; some of the Granville Co. families possibly alternated between there and Warren Co.
Anthony ROBINSON/ROBERTSON was a former slave, previously married to a SUSAN ROBINSON, according to the Warren Co. Cohabitation records, they were married in 1849 as slaves; in 1870, he was married to a "Louise". If you check some of the 1865-1900 Marriages online, you will see a few children listed with parents Anthony & Louise ROBINSON, with one, Sallie ROBINSON,b.abt 1861, listed with parents, Anthony & Lavira ROBINSON. I don't know about the "Louise" (possibly the same person as "Susan") not having seen the actual marriage page myself, but I can tell you that I've had several "Silvia"s incorrectly transcribed with a similiar spelling as "Lavira" in these records, so keep that in mind when looking at some of the names.
Anyway, Sallie ROBINSON married Warren YANCY in 1884, and I have their son, Rex YANCY, b.1885 Warren Co. in my tree because he married Nancy Jane HOWARD,b. 1883, (d/o Henry HOWARD & Ida CARTER)from my CARTER line. There was a Sallie ROBINSON, age 9, in the 1870 h/h of Anthony & Louise, and it's more than likely they listed the step-mother as the mother on the record. I don't see anything on a Majha Eddie Mayo in any of those records, there could be a misspelling somewhere, but you may want to explore both the census and the marriage records to help you identify some of the people you are looking for. Note that the surname has been listed in various records as:
MAYO, MAHO, MAHYO, MAYHO, MAYOE, MAYHOE.
