Owens Mound appears to be a relatively prominent hill, and also appears to stand up as the true high point of Ashtabula County. It is located about two miles west-northwest of Andover.
The original topo depicts a sharply-rising hill that reaches a highest contour of 1190 feet. A benchmark elevation of 1191 feet is also given. The LiDAR DEM agrees very closely with the original topo. The LiDAR DEM also provides a maximum elevation of 1191.6 feet, which matches up fairly well with the elevation of the benchmark. The actual area that rises above 1190 feet is quite small, and appears to be located along the edge of a wooded area.

This area is located 3/4 mile to the northwest of Pennline, and appropriately is located very near to the Pennsylvania state line.
The original topo shows a 1190+ contour in a farm field just west of the state line, and just north of a house. The LiDAR DEM gives a maximum elevation for this area of 1186.6 feet. The LiDAR DEM also depicts a second rise, which appears co-located with the house south of the point discussed above. A maximum elevation for this area of 1185.1 feet is provided. However, the LiDAR DEM suggests that there have been alterations to the terrain in this area.
Since the northern area here is five feet lower than Owens Mound, it is likely not a candidate for the Ashtabula County high point.
Note that higher terrain exists on the Pennsylvania side of the state line, just northeast of the points discussed here.

This is the area 3/4 mile to the west-southwest of Williamsfield.
The original topo depicts this as a very flat area, with only a tiny contour reaching over 1190 feet. The LiDAR DEM also shows the area to be quite flat, and only provides a maximum elevation of 1184.3 feet. The highest ground appears to be associated with some sort of east-to-west running line through the field which the highest contour sits in.
This area does not appear to be in contention.
Despite the obvious differences in elevation provided by the LiDAR DEM and the topo map, it should be noted that in places where spot elevations or benchmark elevations are provided, the two sources almost universally match up within one foot of each other. It is where unchecked contours are drawn on the original topo maps that discrepancies are more likely to be be found (and resolved).

This is the area 1 5/8 miles to the southwest of Williamsfield.
The original topo shows a tiny contour of 1190 feet at this location. The LiDAR DEM actually depicts a discernable hill here, with a highest elevation provided of 1188.6 feet. The highest ground appears to be in a wooded area, and just slightly north of the original 1190+ contour.
The 1188.6 foot elevation should certainly solidify this point as the second highest in the county. However, with a difference of three feet from Owens Mound, it does not appear to be the highest.
