Growth and Spread of the Dulong Family
Richard Dulong has numerous descendants. Most of them live in the province of Québec. Since his two sons who survived to adulthood both moved to L'Assomption County, north, northeast of Montréal, most of the Québec Dulongs have roots in this region known as Lanaudière (see the following table). Some Dulongs moved to New England during the industrial revolution, but they are often confused with Dulins. There are also Dulongs who moved to Ontario. However, most of the Dulongs living outside of Québec are in the Midwest. Many of these Midwest Dulongs descend from François-Édouard "Edward" Dulong who immigrated to Michigan's Copper Country in the mid-nineteenth century. From there his descendants settled in the Detroit area, Montana, Indiana, and elsewhere.
The following table shows the distributions of males and females with the surname Dulong (196), Du Long (1), or Dulon (9) in the United States based on where they were issued their Social Security Number. Keep in mind that the females are usually the spouses of Dulongs and not born as Dulongs.
Although Massachusetts records the largest number of people with the surname Dulong, most of them are from Middlesex County. From the data collected showing the last residence or the last benefit address, which is not reported in the above table, we learn that out of 56 Dulongs in Massachusetts, 32 of them are from Middlesex County. These people are really Dulins and descendants of the Dulins of the Yarmouth area of Nova Scotia. Other Dulongs living in Massachusetts, Maine, and New Hampshire are also likely to be Dulins. Nevertheless, we do know that some Québec Dulongs did settle in Massachusetts in the west and south of the state. Therefore, if you are working with Dulongs in Massachusetts, then you have to carefully research them to differentiate them from the Dulins. See When is a Dulong not a Dulong? When he is a Dulin!
