While it is true that Cape May and Cumberland exchanged land several times (usually for a year or two and not during census years) it was only in Maurice River Twsp (current Eldora, Delmont Cumberland I believe). Millville and Downe were never in Cape May County. Ancestry must be in error in indexing. Bill McLean Fairton, Fairfield Twsp, Cumberland County (once in Salem until the mid 1700's)
