You, the maternal uncle and the maternal grandparents all have a right to seek custody. The basis is that you are a blood relative of the child and leaving the child with your brother (the father of the child) will risk significant impairment of the child's physical health or emotional development. This language is found in the Texas Family Code at Section 102.004 (a)(1).
You may have a leg up over the maternal relatives if your brother will consent to you bringing suit to establish custody of the child. That is Section 102.004 (a)(2).
It is possible that you and the grandparents or you and the uncle could all be named conservators of the child, but the court would name one party the managing conservator who has the right to determine the primary residence of the child.
If you think the child would be better off with you, then you should act quickly to bring a suit for conservatorship.
