March family of PA

Seeking any info on James March m. Marie Buzzard and their family – Arthur, Jacob, Daniel, John Osborne, Sarah E. and William March. Arthur March m. Annie McIntyre? And their children were Willie (died in his teens), James Hilton, Harry Duncan, and Mamie E. March (who also died in her teens). James Hilton March m. Theressa Lancaster, and their son Roy Hilton March is my maternal grandfather.I believe most were born in PA and understand that some of them settled in the PA areas of Pottstown, Stowe and North Coventry. Any info on any of the above and/or their families would be greatly appreciated.
