You need to search the parish records to see if there are others of that name mentioned. A blanket search of all baptisms, marriages and deaths. Hard work but essential. You can get the film from your nearest LDS centre (listed on familysearch.org)
Have you checked the message boards on ancestry.com and rootsweb? Someone was mentioning the Warwickshire family of Angliss. Is anyone doing a one name study? Militia lists? Hearth tax?
Good luck
