Newsletter reader Harold Miller wrote to tell of a new online resource that will interest genealogists with New York City ancestors as well as many historians. In 1811, John Randel created a proposed street grid of Manhattan. Now the New York Times has published his map and other historic information in an online web page that makes it easy to compare the map to modern-day Manhattan.
Harold also wrote, "It took me a while to figure out to click the slide on the left side to change the overlapping views."
You can view the map and the comparisons at http://www.nytimes.com/interactive/2011/03/21/nyregion/map-of-how-manhattan-grid-grew.html?ref=nyregion&nl=todaysheadlines&emc=tha29
NOTE: The New York Times sometimes leaves things in view at no charge for a few days, then moves the pages to the site's archives section which requires payment. The above URL is free and open to everyone as I write these words, but I have no idea how long that will last.
