Where in The World is Lisa Miller and Her Daughter Isabella?

Dec. 30, 2009 — -- A mother and her 7-year-old daughter who is supposed to be handed over to the woman's former lesbian partner on New Year's Day have not been seen or heard from in more than a month, according to the judge in the case.

Lisa Miller, who now lives in Winchester, Va., was ordered by a family court judge in Vermont to hand over Isabella on Jan. 1 to Janet Jenkins, Miller's former partner.

But now, just two days before the handover is supposed to occur, nobody knows where Miller or her daughter is.

"She does not know where her daughter is and she is trying to find her," Sarah Star, an attorney representing Jenkins, told ABCNews.com

Star says Jenkins last saw her daughter in January 2009 and spoke with her in March 2009. In his custody ruling, Vermont Family Court Judge William Cohen said nobody has "seen or heard from" Miller and Isabella since Nov. 20.

The judge ordered custody to be switched from Miller to Jenkins after Miller repeatedly failed to allow visitation for her former partner.

An assistant to the lawyers representing Miller, Mathew Staver and Stephen Crampton, told ABCNews.com that the lawyers were "on vacation and unavailable for comment on the matter."

A Facebook page seemingly set up by Miller appears to show the last posting from the mother being on Dec. 4.

The custody of Isabella has been a point of contention since the couple -- who were married in a civil union in Vermont in 2000 -- split in 2003, after which Miller denounced homosexuality and became an evangelical Christian.

Miller, who became pregnant with Isabella in 2002 through artificial insemination, said in court documents filed by her attorney on Dec. 16 in an attempt to prevent Jenkins from being awarded full custody, that her daughter would undergo "trauma" because of the "different religious beliefs" she would be exposed to living with Jenkins.

"[Isabella] knows that Ms. Jenkins' choice to continue to live a homosexual lifestyle is a sin," says Miller in the court documents. "Ms. Jenkins does not share these beliefs."
