Looking for Brother and Sister

Hello, I am Patricia Ann McKittrick Reinhart, daughter of Alan Crawford McKittrick, and granddaughter of Percy Alan McKittrick of Fitchburg, Mass. My parents divorced when I was 2 years old and the last time I saw my father I was 4 years old. My grandparents always kept in contact with me and even after my grandmother died Gramps still kept in contact with me until his death when I was around 21. I know that I have a 1/2 brother and sister who are both older than me but we have never met. I live in Frisco, Texas with my husband David. We are both retired, him from banking and me from city government. I just happened to Google Percy Alan McKittrick and came upon this site. It was always a desire of my heart to know my father's side of the family. I would love to hear from by brother or sister. Thanks for putting this site out on the web.
