I looked but used an IOM birth as a sort key on Mary Jane and found no one.
Going back, the closest is Mary Jane Ash 3 born Liverpool, in Peplow Shropshire HO107/1996 folio 525 page 3
Thomas Ash 51 Farm labourer b Illerdine Heath Shropshire
Martha Ash Wife 48 b Langbridge Shropshire
Elizabeth Ash daughter 17 b Peplow
Mary Jane Ash visitor 3 b Liverpool

A possibility - they could be relatives - but the date is off. And no trace of the parents.
Cate, do you know the places of birth of James and Sarah Maria?
