Hello, M!
I agree with Steven for the case you describe. You may be adding different sections of the obituary anyway, so just quote (properly!) or reword the relevant information related to each profile.
You may want to follow up (or perhaps do this first) that with a free-space, as Ruben recommends, quoting or linking to the full obituary, if possible. You could then cite/link each quote/excerpt to the free-space (as well as the online source, if any).
