Looking for my siblings

I am not adopted, I have four siblings, two brothers and two sisters who were taken away before I was born.  They are actually my step-siblings, but their as much family to me as my own full blood siblings. They were born with these names, but they have been adopted. It is important that I meet them. Their mom is dying.  I need your help.  Their names are: Linda Sue Villeneuve Born 8-7-1957 in Alpena, MI Barbara Jean Villeneuve Born 9-1-1958 in Curran, MI Leslie William Villeneuve Born 3-10-1961 in Alpena, MI These 3 were taken away first before 1971. They were taken away in Alcona, MI. Laurie Ann Villeneuve & Robert Roy Villeneuve have been found in the next set, still searching for Rex Villeneuve, he has been adopted. Laurie Ann Villeneuve Born 3-3-1962 in Alpena, MI Rex Alan Villeneuve Born 3-25-1963 in Alpena, MI Robert Roy Villeneuve Born 3-2-1968 in Detroit, MI Taken away in Detroit, MI around 1971-1972. Biological Parents of these children are: Leslie Villeneuve Sr. born in Alpena, MI between 1930-1937(middle name, I think is William) and Shirley Ann Villeneuve (maiden name is McClaren)born 5-30-1940 in Flint, MI. The oldest three were in a foster home in Barton City with the Cortis family.  They were adopted out though.  One of the girls were adopted by a family in Hubbard Lake, MI. and the other two were sent to Flint, MI.  If you recognize any of these names, even if it is a wild goose chase, please, please, email me at gougeongenius@yahoo.com. Thank you in advance for all your help.

This is me and my kids, I would like to be standing here with my siblings too.
