Elijah Johnson Service Records

I am trying to tie down the Company my ancestor Elijah Johnson served in during the War of 1812. I know that he was born about 1785 in Virginia, and moved North as a child. He attended a Methodist Seminary in New York, where he was Ordained as a Minister. He was in Pennsylvania from 1808 to 1811, when my ancestor Sarah Johnson and her brother Elijah were born. He was also a member of the American Colonization Society, and emigrated to Liberia in 1820.

Here are the three Units listing Elijah Johnson:
1. 1st Regiment (Harris), New York Militia-Private
2. 2nd Regiment (Ward's), New York Militia-Private
3. Hills Regiment Pennsylvania Militia - Private

If anyone has information on my ancestor or questions, please contact me.
