I do not know of any connection. I am gathering descendants of my great great grandfather Alfred Lamb Blackburn, born in 1849 in Lancashire. I have only a short list of Blackburns beyond him.
Wish I could help. I have gathered quite a large amount of information about Alfred, but beyond his parents I have nothing on the Blackburn line. My Blackburns were Latter-Day Saints, and left England between 1869 and 1890 or so. Alfred's father Samuel was not close to his family, and so I really have very little on his ancestry. I have back to his grandfather on his Blackburn line, but, nothing further despite my efforts.
Vincent is not a name in any of my Blackburn lines--There are quite a few Blackburns out there, and so many lines which connect someplace but no one is exactly sure how.
