It appears Harry & Elizabeth Roberthsaw came to the USA sometime between their marriage in Dec..1899 but before the death of their oldest child Lily who died & was buried in Pa. in 1900.
Harry's father-in-law, Thomas Whitehead, was born in Pendleton, Lancashire, England, United Kingdom. Elizabeth (Whitehead) Robertshaw, was buried in Wilkensberg, Alleghany, Pa. in 1927
