Yes I was aware of the Esther/Elizabeth Lowndes both have been recorded on FS both the same date.
Does FS show the parish record? I can’t see it.
It looks as though it has been transcribed wrongly as Elizabeth is the name transcribed in England, select Marriages’ which is an index.
The parish record page is shown in both Lancashire and Manchester marriages where it is clearly Esther. It is also ‘Lownds’ without the ‘e’ .
Your friend can find the entries on Ancestry.
Lancs opc also transcribes it as Esther.
It may make a difference to your search and your friend’s records.
