I have just completed a booklet with all the BARTLETTs in the MD Census from 1790 to 1930...Is this the line you're looking for:

Muniel M BARTLETT b Sep 1896 MD [T0,1] B. Mary Alice BARTLETT b Apr 1900 MD [T0,1]
Are you descended from one of these last two? I had a ? for Joseph H because he wasn't in the 1850 census; I think you've just provided the reason why. I can't tie Samuel b 1815 to the rest of the Talbot Co, MD BARTLETTs, yet, but I'm sure he fits in somehow.The Talbot Co, MD BARTLETT go back to the 1500s.
