Hello from Tuscon, Arizona, USA. I am Drew Hyatt Seamans. My gr grandmother was Arabella Drew Atkin, daughter of Richard Atkin and Margaret Moore Atkin. Richard was Walter Atkin's brother. Richard came to America in 1850. In 1867 he brought two sisters Alice (or Alicia) and Georgina.
I have more information that might fill in blanks you might have. I haven't much past Walter, Sr. and Alicia Drew. How far back does your research go?
