My great gran was baptised in Oxford in 1895 as a baby then baptised again in London in 1910 when she lived in a Hackney convent for a time.
Perhaps a conditional baptism prior to receiving the sacrament of confirmation. Was she in the convent because she was an orphan or because she couldn't live at home for some reason?
I did post about this in the London board earlier this year. This will give you some more info on the story. Her mother died in 1902 when she was 6 back in Oxford. Her first baptism was at the parish church of St Peter Le Bailey, Oxford in Oct 1895, and she was baptised at St John, Vartry road, Stamford Hill, London in March 1910.

Some of the boys at the Rochdale home may have lost a parent or parents by death or separation at an early age like your GGM and there may have been no one available to verify if a child had been baptised when an infant. Added to that, some of them had moved or been moved around districts, counties and even countries, so knowledge of when and where a baptism might have happened would have been sparse or non-existent in some cases.
Annual numbers of baptisms at the Rochdale orphanage were in single figures in the earliest years of the home's existence, a small proportion of numbers of first communions in those years, so I assume they were only those boys whose families, guardians, teachers or parish priests couldn't verify a prior baptism.
Conditional baptisms at the Rochdale home were more numerous in some years.
There are notes with some baptism entries. A few include extracts of letters from a parent, priest or a nun who may have been a teacher or in charge of another orphanage.
Examples:
1919 page 48, entry 239: A boy named Bernard with 2 surnames, 1 in brackets. Note taped to page "says he's five". (I wondered if the 2 surnames meant he was later adopted or if it was just that he was known by either surname.)
6 Dec. 1921 (entry 271), 24 Dec. 1926 (entry 280): Baptisms of 2 brothers. A note attached to 1921 baptism includes extracts of letters from the boy's mother and from a nun. Mother stated that a third brother was already baptised. She also asked to be informed where her son was to receive his first communion.
There are notes at the end of the baptism register after the final chronological entry 28th October 1933. These include letters from priests and a letter from a former inmate (aged 62) who was trying to trace his birth certificate. Page 64, entries 316-319.
Catholics who married in a Catholic church from Easter 1908 were supposed to have information about their marriage added to their baptism entry. The parish priest where they married wrote to the parish where they were baptised. ("Ne temere" decree on marriage 1907) Marriage information has been added for some Buckley Hall boys.

I've just remembered 2 other Lancashire baptism registers, Burnley workhouse and a Catholic church in Burnley. Some babies were baptised in the workhouse soon after birth. Some of them had "follow-up" baptisms at the church weeks or months later; some didn't.
