Jonas is the son of Terry Sue and the half brother of Tommy. Jonas has a different father than Tommy, whose father is Pops, the grandfather of Quinn Blackwood, the owner of Blackwood Farm. Because Tommy is technically Quinn’s much younger uncle, Quinn takes care of Terry Sue and her children, so that Jonas and his siblings can receive an excellent education and have a hopeful future.
Jonas appears in Blackwood Farm (2002). For more perspectives on Jonas’s character, read the Alphabettery entries Blackwood Farm, Quinn Blackwood, Terry Sue Harrison, and Tommy Harrison.
