Maryland Gov. William Donald Schaefer yesterday appointed three Maryland attorneys to fill vacancies on the District Courts of Montgomery, Prince George's and Baltimore counties.

Schaefer appointed Charles Elsworth Foos III to the 3rd Judicial Circuit for Baltimore County, John Francis Kelly to the 7th Judicial Circuit for Prince George's County and Paul Ambrose McGuckian to the 6th Judicial Circuit for Montgomery County.

Kelly, who will serve Prince George's County, will fill the vacancy created by the retirement of former Judge Irving Fisher.

Kelly received a bachelor's degree from Providence College in 1955 and a law degree from the Georgetown University School of Law in 1960. He is a partner at Caulfied, Kelly and Holler of Mount Rainier, and he is a member of the Attorney Grievance Commission Inquiry Committee.

McGuckian, who will fill the Montgomery County vacancy created by the retirement of Judge Charles Woodward Jr., received a bachelor's degree from Dickinson College in 1960 and a law degree from George Washington University Law School in 1964.

McGuckian is the county attorney for Montgomery County, and he serves on the Board of Directors of the Montgomery County Bar Foundation.

Foos, who will fill the vacancy resulting from the death of Baltimore County Judge James Kardash, is a panel lawyer for the state of Maryland Defender's office and a partner at Romadka, Gontrum, Hennegan and Foos.

Foos graduated from the University of Maryland and received a law degree from the University of Baltimore in 1965.

Foos, a member of the Attorney Grievance Commission Inquiry Committee, was elected to the Executive Council of the Baltimore County Bar Association in January.

The three appointments are effective upon qualification and are subject to confirmation by the state Senate. District judges are appointed for 10-year terms and may serve successive terms.
