Looking for Lyman H Ward

I am looking for any information about Lyman H. Ward, born in VT in 1820, married Mary E. Chesebrough and moved to TX in the 1860s. Two children--John W. and Ada.

Lyman was a sailor who came to the TX Gulf coast with his family right before a hurricane and the Civil War ended all shipping. He served in the state guard during the Rebellion and then later became a Justice of the Peace, then a surveyor. (We traced all this through state census) His son John also became a surveyor in Victoria County, TX. John is my great grandfather.

I think Lyman and Mary died around the turn of the century in Houston. They lived with their daughter and son-in-law, James and Ada Fogarty. I'd like to find out who Lyman's parents were.

Also I would like to find their graves in Houston, TX.
