Hi Judy.....there are 3 Lock listings in the 1850 Wmsn.Co.,TN census. one of them is in District 6, #844, Williamson Co.,TN poorhouse...Drucilla Lock, age 31, born in TN. Listed for the Isaac Twomey household, Isaac ran the county poorhouse at the time. The other 2 listings are both in the District 3 area, and are fairly close together. They are the reason I said the Lock's may have Grissom & Brown connections. They follow, and there are no more listings for Lock in the 1850 census. I have a few more records here at home I can look through and will keep an eye out for your Locks.
