First, I have to say, there were a gazillion Crawfords in Holmdel, in the past, and many of them named William!
Here are some of ours...maybe a connection?
John Murray Crawford, a carpenter, b.Aug 6, 1877 d.Jan 13,1940 m. Lavinia Conner
John Murray is son of William R.Crawford, a butcher, later a carpenter, died Oct 16, 1930 married to Ellen Braheny, died 1915.
William R. is son of William G. Crawford, a shoemaker b.1808 d. 1870 who on Dec. 5, 1838 married Maria S. Stillwaggon. They lived in Raritan in 1850.
William G. is son of Gilbert Crawford, married to Amey VanCleaf. Gilbert is a 'dead end' to me, so to speak, but we have more for Amey.
Please let me know if you think there might be a connection.
