Hi Kim
You're in the wrong period to find records on IGI for Jane and her siblings. IGI records in the main are available up to 1875, records after this period are few and far between and are entries that have been submitted.
You will probably have to start by viewing her parents marriage cert on SP. There's an entry in 1882 for the marriage of a John Taylor and Jane Hunter in Bothkennar, Stirling. You will then have to work off the 1891 and 1901 censuses to gather info on Jane's siblings. You can then view individual birth certs for her and siblings on SP. There is for example a birth entry for a Jane Taylor in 1891 in Bothkennar which could be your Jane's.
From her parent's marriage cert. and details of their parents, you can then venture back into IGI for details of their siblings, births etc.
Regards.
Monica
