In 1925 it was noted that an early burial ground existed in a field a short distance to the south of Rhoslanog farmhouse. A curving boundary is visible on first edition Ordnance Survey mapping. If it represents an enclosure, it would measure some 20m north-south. The farmhouse wall is the findspot of Mathry 2 (NPRN 423412), a cross-incised stone thought to date to the 7th-9th century. First edition Ordnance Survey mapping depicts a number (8+) of stones in fields to the north and east of the farmhouse, although they may have been erected as cattle rubbing stones.
