That was the title of Irving Berlin's musical, he wrote while stationed at Camp Upton in WW1 . Camp Upton which became Brookhaven National Lab, had it's postal address as Yaphank then. It was also a major stop on the Long Island Rail Road. It may also of been the first official address of "Clairedale Kennels" There is a book published in 1926 titled "CHOW - THE CHOW CHOW" that lists Clairedale Kennels of Yaphank, Long Island. Claire was showing Chows in the very early 1920's, which would of meant her dogs were being raised in Mastic Beach too. She could of very well been involved with dogs long before that, because her grandfather, J .F. Knapp was one of the co founders of Westminster Kennel Club in 1876. Originally the club was formed for sportsman to show their sporting dogs at the Westminster Hotel. Her father J. P. who was 12, at W K C's beginning, was also a member.
Whatever brought her to Yaphank, she did not go alone. Willis Oliver Penney was with her. They may of arrived there as The Penney's, as I do not know the exact date they were married. I do know her last name was Penney in December of 1925, when she transferred ownership of the Mastic Beach estate to her brother. Her address on the deed is Yaphank. I also know the Penney's lived in Yaphank for at least 3 years or more and at least one of their two daughters was born there. When they sold the 8 acre Yaphank Property in July of 1929, the deed describes the property as being situated and bordered by properties of Weeks, Baker, Swezey, Overton families etc. This 1917 Map shows a small piece of property by the Weeks and near The Suffolk Club which was a Hunting Lodge ( now Southaven Park ) August Belmont was involved with and so was J . P. Knapp
