Since 2002 I have lots more information re my American kin.
Though I did not know about Phyllis in your branch.
My research covers the three sons who went to America:- William, James and Thomas and grandson John, son of Janet. Agnes Carlyle did emigrate to the USA (Pennsylvania in 1881) with sons Thomas and Robert, but I cannot find any details of when and where she died. James lived in Michigan, William lived in Pennslvania and Robert died early.
