We are in need of advice and assistance. Peter Marion Lee resided in Alexandria, LA in 1850 in the Robertson household. He was 17 and was working as a clerk in the Robertson store. In 1860 he lived in Alexandria, occupation dentist, with his wife Eleanor Walter of Maryland; and his children Walter, Annie Rebecca, and Mary. We found him in New Orleans in 1880, occupation dentist, residing with his family. He does not appear in the 1890 census in New Orleans; though his wife is listed, but not as a widow. We have been unable to find his birth place, other than LA; his parents; marriage date; death date or where he was buried. We do know he was born in LA about about 1833. If anyone can help locate information we would appreciate receiving it. We have searched what seems to be every cemetery in LA. He is not buried with his wife in New Orleans. What school would he have attended for dentistry? Perhaps somewhere in Maryland, since his wife is from Maryland. Thank you for any and all help. June
