1881, 1891, and 1901 British censuses all have different birthplaces listed for Laura.
The last record of her is appears to be in the 1910 U.S. census, living with her husband and two daughters in Morenci, Graham County, Arizona with the last name spelled "Andrew." Her husband naturalized in 1903 in Graham County under the last name "Andrews." In the 1921 British census, her daughters Doris and Laura are listed with the notation that their mother is deceased, and in this census James has already married Annie Southcott, which also happened in 1921. So Laura died sometime between 1910 and 1921.
