Hello Al-Pal, I have had some success finding info for you and have asked for copies to be posted to me when ready, as I may not get back to the archives before leaving Cape town, although I would like to if possible. I ran out of time before getting through all the documents you listed. The docs for William Lucas Van Ass could not be copied due to their deteriorating condition but have noted down most of it. The surname is definitely Van Ass and wondered if you still want these details. If you pm me with your e-mail address I will send everything on as soon as it arrives. In the meantime I noted down some of the details for Phoebe Williams Lucas, nee White.
Father, Thomas, Mother, Jane, Husband, Joseph Benton Lucas. She died a widow age 50 on 30.11.1901 Children - William Benton, Alice Phoebe, Francis Rupert (or Robert ), Eliza Josephine.
