The developer who plans to build a housing subdivision on the site of the national golf course of the Washingtonian Country Club near Gaithersburg said yesterday he will preserve, and possibly commemorate, a plot on which a neighboring farmer, Elizabeth Beall Banks, believes her ancestors are buried.

Jay Alfandre said he had heard stories about a cemetery on the site where he wants to build 710 units, but that when he searched property records and talked to recent owners of the land northeast of Muddy Branch Road and Rte. 28, no one could specify its location or show it existed on the 148-acre tract.

Last Thursday, the Montgomery County Planning Board approved Alfandre's request to build a subdivision on the site with no stipulations about preserving a graveyard.

But Alfandre said he altered his plans after reading a story in yesterday's Washington Post in which a county historian, the builder of the golf course and Banks identified a cluster of trees where they believe the cemetery was located.

He said he wanted to make sure Banks and the man who built the golf course were talking about the same spot, and if so, "we're going to put a little wrought-iron fence up, put up a little plaque, and leave it alone."

Noting that Banks said her grandfather moved some of the bodies to Gaithersburg decades ago, Alfandre added, "Maybe if there are still some remains left in the site, we could finish the move."
