Peggy
Sorry for the delay. I've been off list for a time.

No. The Churchill Y-DNA signatures must be from a surname CHURCHILL male. Only males carry the signature. It is passed father to son.

There are 3 types of DNA inheritance patterns that DNA markers follow:

the Autosomal DNA line,
the paternal DNA line,
the maternal DNA line.

Autosomal DNA makes up the majority of who we are. It is composed of all the DNA in the cell except:
X-chromosome,
Y-chromosome
mtDNA.

You inherit 50% of your autosomal DNA from your mother and 50% from your father. In quantity the Autosomal DNA makes up the majority of cell instructions.

Y-chromosome DNA markers are paternally linked. They are passed only from father to son.

The mtDNA markers are maternally linked. They are passed from the mother to all of her children both male and female. Only females normally pass the mtDNA instructions.

the maternal DNA line which is mt-DNA.

X-chromosome,
Y-chromosome
and mtDNA.

Autosomal DNA is the primary construction and maintenance set for the body whether it be male or female. You inherit 50% of your Autosomal DNA from your mother and 50% from your father. In quantity the Autosomal DNA makes up the majority of cell instructions.

MtDNA markers are maternally linked. That is they are normally passed from the mother to ALL of her children both male and female. Having said that, it turns out that on rare occasion a male will pass his mtDNA instructions.

When this happens the child ends up with mtDNA that is some combination of DNA from both the mother and the father.
This is likely a Mother Nature Fail Safe function to ensure preservation of the species through diversification.

Functionally MT-DNA determines and controls how the body cells metabolize sugars.

Y-chromosome DNA markers are paternally linked. They are passed only from father to son. Basically, Y-DNA is a set of conversion instructions. If the egg ends up with Y-DNA the otherwise female fetus will be converted to the male configuration.

If Y-DNA instructions are not present the fetus will develop into a female (mother natures default configuration).
