I think I figured it out.
To find the new Latitude use the Hc formula but for declination use the arcosine of the distance travelled divided by the radius of the earth in nm. LHA is course bearing. Ap Lat. is the Latitude of origin.
To find the Longitude use the typical formula to obtain Zn with the Latitude, obtained above, as the Hc. Once you get the answer, subtract or add it to Longitude of origin.
Mathematically there has to be some way to determine whether to subtract or add the result from the Longitude of origin.
This probably needs some refinement....but for the moment it worked.
