I just did the same thing--well not FB--but I went looking in DobeQuest and after looking at several pedigrees from dogs who were either registered as Bel-Mar something v MnM or MnM something v BelMar I vaguely remember from several years back that there was a new breeder who was being mentored by (duh!--whatshername--BelMar--Priscilla Bell?).I found them on FB. Looks like the current litter is sired by CH HQ Rock My World CD, THD, ROM, CGC CHIC but I can't find the registered name of the dam. They seem to have bred with Bel-mar before. Don't know if that's helpful.
And I just went back to DobeQuest to look at the HQ dog's pedigree. He's pretty well line bred on Oozi--can't think of the kennel name Arabian Knight--a dog I knew well because he started his career out here in the PNW--that pedigree has a lot of longevity.On their FB page they only mention the dam's call name "Juno", I think, and I can't find a dog by that call name in DQ with the MnM listing.
