Not sure but his Twitter has him down as Marcus Anthony Myers Harness so I'd imagine that his mother is Myers.
He's from Coventry as well. I'm not particularly familiar with the trends there but we have had a few players qualifying for us from Coventry down to grandparents. Shipley, Christie and James Maddison. Collins is Coventry too - not sure if he's parent or grandparent. Solihull and Birmingham are close by and have produced plenty in recent memory too which are down the grandparents including Crowley, Grealish, O'Hare. Callum Robinson was born in Northampton which isn't far off either. Think he grew up with Grealish though so probably closer to Birmingham.
