I've been trying to follow up the Frederick Hoyland who was baptised in Louth in 1822 if I remember correctly. In 1851 there’s a 28 year old Frederick Hoyland living at Mount Pisga, Wilham (or Witham?) Road, township of Ecclesall Bierlow, borough of Sheffield (HO 107/2337, f.614, p.12). His birthplace is shown as South Lincolnshire: I wondered if this might be a transcription error, on the part of the census enumerator, for Louth, Lincolnshire.
He was unmarried, an engraver, with an 18 year old servant (Elizh. Haywood) and a visitor (originally listed as his servant also, then corrected) 16 year old Sarah Ann Nixon.
We’d expect this Frederick to be around 18 years old at the time of the 1841 census, but if the instructions were being obeyed his age should be rounded down to 15. So perhaps this is the correct household, in Gill (or Gell?) Str., Sheffield (HO 107/1338, book 7, f.12, p.17):
Elizabeth Hoyland, 30, schoolmistress, y
Frederick do, 15, engraver’s ap., n
Ellen do, 15, n
Hannah do, 7, y
(in a separate household in same building) William Slack, 6, y
At first I wondered if Elizabeth was an older sister of Frederick. However, if I am looking at the correct 1851 census for her (in Gell/Gill St again, HO 107/2338, f.466, p.7), she was a widow:
Elizabeth Hoyland, head, widow, 41, teacher, b. Sheffield
Hannah Maria do, visitor, u, 17 [birthplace appears to be blank]
Ellen do, do, u, 25, teacher of music, b. Louth
Lucy B….iffe(?), do, 6, scholar, b. Hull
Emma(?) Haywood, servant, 27(?), house servant, b.Sheffield
From post #17 there is an Ellen Hoyland in Louth in 1851 with her widowed mother Sarah: she is also a 25 year old teacher of music, born in Louth, like the one in Sheffield. It seems this may be a case of one person being enumerated twice, unless there were two Ellens both born in Louth around the same time who both became music teachers.
