Hi Snowy, LKE and Rosie for your very informative advice, greatly appreciated. Family cousins from out of town, whom we havent seen for years, visited mothe-in-law at the Alzeheimer's unit. She was plesant but did not recognize any of them. So we decided not to disturb the present state she is in and to leave well enough alone. Somewhat fearful of causing a state of agitation. We informed the nursing home staff of our decision. Hopefully we have made the right decision for her and also us. Thank you for your input, it was very helpful.
