I've found a likely baptism on the IGI for a Mary Crawshaw, daughter of Thomas Crawshaw. It's in 1773 in Ripponden. She married in Almondbury but I haven't been able to find a baptism for her there. Infact, not many Crawshaws at all in Almondbury. Ripponden doesn't look to be far away on the map.
I thought I could try to trace her ancestors in Ripponden, but, if it's anything like Almondbury, you really need the baptism transcriptions which hopefully include the area where the baptism took place because, unless you're very lucky, there always seems to be millions of people with the same surname - and no mother's name given!!
However, I've just found a possible marriage for her parents in nearby Elland in 1755 (Mary would have been one of their youngest children).
So now I'm really confused! Although I think Elland also comes under Calderdale FHS?
