Charles County, Maryland Relatives of the Langley Family

Hello,

I am looking to pick the brain of someone who is of the Langley family and who's branch of family is also related to the following families:

Kendrick
Gilroy
Moore
Rye

and possibly:
Franklin
Montgomery

The time period most interested in is the 1800s time frame.

Thanks in advance for any help anyone can be, Wanda
