How to draw language family tree in LaTeX

Question

I have been attempting to draw this language family tree into LaTeX: I have tried using the tikz package as well as the forest package, but to no avail. I do not need the colours in the tree, nor do I need the lines to be formatted in the same way, but just for the lines to go to the correct language(s).

This is the code I have now (I have not included the "Baltic" branch, as it is not absolutely neccesary):

\documentclass[a4paper, 11pt]{book}
\usepackage{lipsum} %This package just generates Lorem Ipsum filler text. 
\usepackage{fullpage} % changes the margin
\usepackage{forest}
\usepackage{showframe} % just to show the margin lines; comment this package     out for the final version

\begin{document}

\section*{Language tree}

\begin{forest}
for tree={
    edge path={
        \noexpand\path [thick, \forestoption{edge}] (!u.parent anchor) --   +(0,-7pt) -| (.child anchor)\forestoption{edge label};
}, % this option together with setting the parent and child anchors to south and north, respectively, gives you the right-angle style for your branches
parent anchor=south,
child anchor=north,
align=center, % allows you to put line breaks within nodes
}

                ]
            ]
        ]
    ]
]  
]
\end{forest}

\end{document}

These are the errors I receive:

Is it possible to do this in LaTeX?

(I am using XeLaTeX compiler)

Thank you for any help in advance.

As requested by the OP, I paste a version that compiles. I have starting shuffling closing brackets ] but not finished it. -marmot

I'm doing a family tree and ran across this package built for just that - might work here as well. https://www.ctan.org/tex-archive/macros/latex/contrib/genealogytree
