Your post looked interesting so I did a search on Ancertry.com. I used the keys shown in the Screen Shot below.
That returned what is shown in the Screen Shot below.
I clicked on what the red arrow points to and got found what is shown in the Screen Shot below.
I know it does not show where Asa was burried, but it does show that he might have taken the last name of his wife Mary Plimpton since the children carry that last name.
Also, since the name is listed as Major Asa, this info could lead you on a wild goose chase if "Major Asa" is not "Asa Bailey Major".
Hope this helps, sorry if it does not.
