Yes, Captain Zenas Wheeler did serve under Colonels Hopkins and Ashley. His son, Zenas, also served and was involved in the march to Saratoga. Check the Massachusetts Soldiers and Sailors in the Revolution and you should find information on both of these soldiers. I know they are listed under the SAR records too. Didn't Beulah Wheeler married a Howe?

As you can tell, they are also my great grandparents. It is a little confusing with both Zenas' fighting in the war. I am not certain they have been listed in the DAR. They should be. Good luck. Contact me at jvsaints@gmail.com if you want. Thanks.
