Hi,
Have you had a look at the 1901 census yet? From the free-to-view index Henry Butterworth would appear to be a widower:
Sarah Butterworth, age 24, born Liverpool
John Butterworth, age 28, born Liverpool, general labourer
Francis Butterworth age 2, born Liverpool
Henry Butterworth, age 55, born Manchester, cooper
There is also:
Albert Butterworth, age 27, born Barrow in Furness, shipwright
Elizabeth Butterworth, age 26, born Liverpool
Elizabeth Butterworth, age 1, born Liverpool
William Butterworth, age 33, born Liverpool, dock labourer
Mary Butterworth, age 30, born Liverpool
Thomas Butterworth, age 31, born Liverpool, dock labourer
Elizabeth Butterworth, age 30, born Liverpool
Alice Butterworth, age 9, born Liverpool
All the above are in Toxteth Park.
Regards,
Sasha.
