The Borders Family History Society has published a booklet of Ancrum and Longnewton monumental inscriptions.
Nigel Hardie has transcribed and published parish of Ancrum mortcloth records for 1733-1850.
A list of pre-1855 gravestone inscriptions in Bewlie cemetery is given in the following volume:
Gravestone inscriptions prior to 1855: Vol 2. Galashiels Old Cemetery, Ladhope and Bewlie Cemeteries
published by Selkirkshire Antiquarian Society, 1969 (listed in the LDS Family History Library catalogue in microfilm format, so hopefully available worldwide in LDS family history centres).
The creator of these pages is unsure of the exact location of this cemetery which may lie within Lilliesleaf parish. Burials of people from both there and Ancrum parish are listed.
