Parenting after a separation is never straightforward, and many parents worry most about how their children will cope. It can help to gently remind children – more than once – that the separation is an adult decision and never their fault, while keeping routines as consistent as possible across both homes.

Sharing a calendar, speaking directly with your co-parent instead of sending messages through your child, and avoiding criticism of the other parent in front of them can all reduce stress and loyalty conflicts. If you notice anxiety, behaviour changes or a dip at school, reaching out for professional support is a strong step, not a failure.

If a question of parentage is part of what you are facing, That DNA Company can help you explore this privately. Read the full article on our blog or call 0203 603 1189 for a confidential chat.

“Family stories can only take you so far.”

Memories, assumptions and long-held beliefs can leave important questions about family relationships unanswered. When you need more than stories, a discreet DNA relationship test can help show whether a claimed biological relationship is supported by the genetic evidence, handled carefully from start to finish in our UK laboratory.

If you’re facing a sensitive situation and want clear, straightforward information, our latest blog explains how DNA relationship testing works and what to expect. Read the full article on our blog and call 0203 603 1189 for a confidential conversation.

How accurate is a DNA test – and what actually affects the result? In our latest video and blog we explain, in plain English, the five key factors that matter most.

From the type of relationship being tested, to the quality of the samples, the number of genetic markers analysed, the way the test is carried out in our own UK laboratory, and how your results are interpreted – it all plays a part.

If you’re considering a private DNA relationship test and want clear, honest information, read the full article on our blog and call us on 0203 603 1189 to talk through which test fits your situation.

At That DNA Company, we provide private DNA relationship testing to help give clear answers about family connections.

Our tests compare inherited genetic patterns between two or more people to show whether a claimed biological relationship is supported by the genetic evidence. We offer paternity, sibling, grandparent, aunt/uncle and twin zygosity tests, all using a simple cheek swab taken at home.

If you’re unsure which test is right for your situation, you don’t have to work it out alone. Read more on our blog and call 0203 603 1189 to talk through which test fits.

Did Thomas Jefferson father children with Sally Hemings, a woman he enslaved? For nearly 200 years, the answer remained uncertain, especially as there was no DNA from Jefferson himself to test.

A recent 2026 preprint has revisited this question using genetic material from a preserved lock of hair attributed to Jefferson, compared with living descendants. The early findings suggest patterns consistent with Jefferson ancestry in descendants of both Martha Wayles Jefferson and Sally Hemings. This is still preliminary work and has not yet been peer reviewed, so it should be read with care.

In our latest blog, we explore what this historic case can teach us about modern DNA relationship testing. Read the full article on our blog and contact us on 0203 603 1189 to talk about relationship testing.

Thinking about a DNA test but worried about where your information goes?

That DNA Company is a UK-based team with over 20 years’ experience in DNA testing. Your samples are processed in our own laboratory in County Durham, so your Personal Information DNA Testing never leaves our care or gets outsourced overseas.

Home kits are dispatched the same or next working day, and once your samples reach our lab, results are typically available within 2 working days. Throughout, your details are handled discreetly, securely and with the sensitivity this kind of testing deserves.

If you or your family are considering a private DNA test, it may help to know everything is handled here in the UK by an experienced, confidential service.

Worried a DNA test will be complicated or time-consuming?

Here’s how our non-legal home swab tests are designed to work as simply as possible:

• You place your order online or by phone and we send your kit out by post.
• Your kit arrives with clear instructions and everything you need to collect cheek swab samples at home.
• Once you’ve taken the samples, you pop them into the pre-paid return envelope.
• When the samples reach our UK laboratory, our team starts testing.
• Results are then delivered securely online, usually within 2 working days of the lab receiving your samples.

If you’re local to County Durham or nearby, there’s also an option to attend our clinic for sample collection instead of using a home kit.

If you have questions about any step in the journey, you’re not alone – many people do. You can always ask for clarification before deciding what feels right for you.
