Beach family in Detroit metro area 50's thru 80's
Son Charles is a baby boomer.
Father Herbert Lincoln (family lived in Miami 20's) and moved to Detroit 40's.
Herbert was a graduate of Lawrenceville Prep and attended Yale.
Herbert had one sister lived in MD (50's thru 90's).
Other than that I have no further info.
Need input especially on Grandfather in Miami time period.
